Hausmann, R., Santos, M.A. & Obach, J., 2017. Appraising the Economic Potential of Panama: Policy Recommendations for Sustainable and Inclusive Growth.Abstract

This report aims to summarize the main findings of the project as gathered by the three baseline documents, and frame them within a coherent set of policy recommendations that can help Panama to maintain their growth momentum in time and make it more inclusive. Three elements stand out as cornerstones of our proposal:

(i) attracting and retaining qualified human capital;

(ii) maximizing the diffusion of know-how and knowledge spillovers, and

(iii) leveraging on public-private dialog to tackle coordination problems that are hindering economic activity outside the Panama-Colón axis.

Bahar, D., Molina, C.A. & Santos, M.A., 2017. Fool’s Gold: On the Impact of Venezuelan Devaluations in Multinational Stock Prices.Abstract

This paper documents negative cumulative abnormal returns (CARs) to five exchange rate devaluations in Venezuela within the context of stiff exchange controls and large black-market premiums, using daily stock prices for 110 multinationals with Venezuelan subsidiaries. The results suggest evidence of statistically and economically significant negative CARs of up to 2.07% over the ten-day event window. We find consistent results using synthetic controls to causally infer the effect of each devaluation on the stock prices of global firms active in the country at the time of the event. Our results are at odds with the predicaments of the efficient market hypothesis stating that predictable devaluations should not impact stock prices of large multinational companies on the day of the event, and even less so when they happen in small countries. We interpret these results as suggestive indication of market inefficiencies in the process of asset pricing.

Coscia, M., Cheston, T. & Hausmann, R., 2017. Institutions vs. Social Interactions in Driving Economic Convergence: Evidence from Colombia.Abstract

Are regions poor because they have bad institutions or are they poor because they are disconnected from the social channels through which technology diffuses? This paper tests institutional and technological theories of economic convergence by looking at income convergence across Colombian municipalities. We use formal employment and wage data to estimate growth of income per capita at the municipal level. In Colombia, municipalities are organized into 32 departamentos or states. We use cellphone metadata to cluster municipalities into 32 communication clusters, defined as a set of municipalities that are densely connected through phone calls. We show that these two forms of grouping municipalities are very different. We study the effect on municipal income growth of the characteristics of both the state and the communication cluster to which the municipality belongs. We find that belonging to a richer communication cluster accelerates convergence, while belonging to a richer state does not. This result is robust to controlling for state fixed effects when studying the impact of communication clusters and vice versa. The results point to the importance of social interactions rather than formal institutions in the growth process.

Santos, M. & Reinhart, C., 2016. From Financial Repression to External Distress: The Case of Venezuela. Emerging Markets Finance and Trade , (Jan. 2016) , pp. 1-30. Publisher's VersionAbstract
Recent work suggests a connection between domestic debt and external default. We examine potential linkages for Venezuela, where the evidence reveals a nexus among domestic debt, financial repression, and external vulnerability. The financial repression tax (as a share of GDP) is similar to OECD economies, in spite of higher debt ratios in the latter. The financial repression “tax rate” is higher in years of exchange controls and legislated interest rate ceilings. We document a link between domestic disequilibrium and a weakening of the net foreign asset position via private capital flight. We suggest these findings are not unique to Venezuela.

Santos, M., 2016. The Right Fit for the Wrong Reasons: Real Business Cycle in an Oil-Dependent Economy. Latin American Journal of Economics (former Cuadernos de Economía) , 53 (1) , pp. 61-94. Publisher's VersionAbstract
Venezuela has an oil-dependent economy subject to large exogenous shocks and a rigid labor market. These features go straight to the heart of two weaknesses of real business cycle (RBC) theory widely reported in the literature: neither shocks are volatile enough nor real salaries suf ficiently flexible as required by the RBC framework to replicate the behavior of the economy. We calibrate a basic RBC model and compare a set of relevant statistics from RBC-simulated time series with actual data for Venezuela and the benchmark case of the United States (1950–2008). Despite Venezuela being a heavily regulated economy, RBC-simulated series provide a good fit, in particular with regard to labor markets.

O'Clery, N., Gomez-Lievano, A. & Lora, E., 2016. The Path to Labor Formality: Urban Agglomeration and the Emergence of Complex Industries.Abstract

Labor informality, associated with low productivity and lack of access to social security services, dogs developing countries around the world. Rates of labor (in)formality, however, vary widely within countries. This paper presents a new stylized fact, namely the systematic positive relationship between the rate of labor formality and the working age population in cities. We hypothesize that this phenomenon occurs through the emergence of complex economic activities: as cities become larger, labor is allocated into increasingly complex industries as firms combine complementary capabilities derived from a more diverse pool of workers. Using data from Colombia, we use a network-based model to show that the technological proximity (derived from worker transitions between industry pairs) of current industries in a city to potential new complex industries governs the growth of the formal sector in the city. The mechanism proposed has robust strong predictive power, and fares better than alternative explanations of (in)formality.

O'Clery, N. & Lora, E., 2016. City Size, Distance and Formal Employment.Abstract

Cities thrive through the diversity of their occupants because the availability of complementary skills enables firms in the formal sector to grow, delivering increasingly sophisticated products and services. The appearance of new industries is path dependent in that new economic activities build on existing strengths, leading cities to both diversify and specialize in distinct areas. Hence, the location of necessary capabilities, and in particular the distance between firms and people with the skills they need, is key to the success of urban agglomerations. Using data for Colombia, this paper assesses the extent to which cities benefit from skills and capabilities available in their surrounding catchment areas. Without assuming a prioria a definition for cities, we sequentially agglomerate the 96 urban municipalities larger than 50,000 people based on commuting time. We show that a level of agglomeration equivalent to between 45 and 75 minutes of commuting time, corresponding to between 62 and 43 cities, maximizes the impact that the availability of skills has on the ability of agglomerations to generate formal employment. Smaller urban municipalities stand to gain more in the process of agglomeration. A range of policy implications are discussed.

Coscia, M., Hausmann, R. & Neffke, F., 2016. Exploring the Uncharted Export: An Analysis of Tourism-Related Foreign Expenditure with International Spend Data.Abstract

Tourism is one of the most important economic activities in the world: for many countries it represents the single largest product in their export basket. However, it is a product difficult to chart: "exporters" of tourism do not ship it abroad, but they welcome importers inside the country. Current research uses social accounting matrices and general equilibrium models, but the standard industry classifications they use make it hard to identify which domestic industries cater to foreign visitors. In this paper, we make use of open source data and of anonymized and aggregated transaction data giving us insights about the spend behavior of foreigners inside two countries, Colombia and the Netherlands, to inform our research. With this data, we are able to describe what constitutes the tourism sector, and to map the most attractive destinations for visitors. In particular, we find that countries might observe different geographical tourists' patterns - concentration versus decentralization -; we show the importance of distance, a country's reported wealth and cultural affinity in informing tourism; and we show the potential of combining open source data and anonymized and aggregated transaction data on foreign spend patterns in gaining insight as to the evolution of tourism from one year to another.

Hernandez, I. & Monaldi, F., 2016. Weathering Collapse: An Assessment of the Financial and Operational Situation of the Venezuelan Oil Industry.Abstract

Venezuela has one of the most abundant geological endowments in the world. Oil proven reserves are among the largest globally, even if a more conservative criterion than the one used by the current government is applied. However, these resources are qualitatively different than those of other abundant regions such as the Middle East. The large majority constitutes extra-heavy oil, which generally requires higher oil prices to be extracted profitably.

During the last decade, the Venezuelan oil industry wasted a unique opportunity to increase investment and production. At the high oil prices that prevailed, the massive oil reserves could have been monetized by rapidly increasing production with a large margin of profitability. Quite to the contrary, production steadily dropped due either to lack of investment in the new unconventional oil projects or for failing to compensate the decline of the older conventional fields. It is a tragic story of great potential with dismal performance.

A series of trends were negatively impacting the Venezuelan oil industry even before the oil price collapse in 2014. From the revenue side, although oil prices showed an increase in real terms of 120% between 2000 and 2014, the barrels that effectively generate cash for Venezuela have shown a continuous decline. This is not just because production has been declining for the most part during the last eighteen years (a trend that has gotten significantly worse during the last year), but also because of a number of developments. First, during that period, total exports have declined more rapidly than production, and recently, net exports have declined more than total exports. Consumption in the massively subsidized domestic market increased until 2013 (when it started to decline likely because of the recession in the local economy), while imports of oil products for the domestic market have increased since 2012. The domestic market not only generates negative cash-flow for the national oil company (NOC), PDVSA, but also its expansion reduced the barrels available to export. More recently, there has also been an increase in imports of light oil and naphtha as diluents for the extra-heavy oil. Second, the Venezuelan production basket has become heavier and the share of unconventional production, generally less profitable, has increased. Third, the production wholly operated by PDVSA has been falling much more rapidly, while the production share of joint-ventures increased. Fourth, a significant share of the exports to Latin America and the Caribbean is subsidized (although these exports have declined recently). Fifth, some oil exports are committed to repay debts of PDVSA and specially the Venezuelan government, limiting the actual cash flow received by the company. In particular, the government’s debt agreements with China involve a significant and increasing amount of production, although recently those agreements were restructured, allowing for a grace period with no capital amortization. From the expenditure side, PDVSA was increasingly responsible of carrying social expenditures and activities not related to the oil industry, which limited the resources for highly profitable investments. That is in addition to the increased fiscal take due to changes in the tax legislation. Also, higher investment requirements due to an increase in the equity share of PDVSA in joint venture projects, has had an impact on its cash flow.

The explanations for the underperformance of the Venezuelan oil industry basically fall into two connected categories: the multiple problems facing PDVSA; and the increase in above-ground risks for foreign investors operating in the country. The deterioration of the institutional framework, led to radical fiscal and regulatory changes, and to the nationalization of the majority of the industry. In 7 addition, the substantial over-extraction of resources from the NOC, the significant macroeconomic distortions affecting the cost structure of oil companies, and the constraints imposed by the energy infrastructure and human capital availability; have combined to produce dismal results. The massive firing of the majority of the management and technical experts from PDVSA in 2003 following the political conflict that led to a strike, has left the company with limited capabilities to operate effectively.

The recent decline in oil prices, and the changes in the international market structure, have exposed more dramatically the difficulties facing the Venezuelan oil sector, and call into question its ability to prevent a continuation of the declining trend in oil extraction. This situation becomes particularly severe if we take into account the cash flow constraints facing PDVSA, as well as its multiple operational problems, power cuts, and conflicts with oilfield services providers. These challenges are proportional to the enormous investments required to finance the projects in the Orinoco Oil Belt, where most of the reserves in Venezuela are located, and where the quality of the crude and the lack of development of the region, are just two of the many issues that need to be addressed.

Since this paper is part of a wider project to understand the macroeconomic challenges facing the country in 2016-17, it focuses narrowly on the financial problems of the oil industry in the short-term and the operational challenges that could impede its recovery in the next couple of years. Within this context, it largely analyzes the upstream operations, i.e. oil extraction, rather than the downstream, given that in the former is where the oil rents are generated and constitutes the main source of foreign exchange and fiscal revenues of Venezuela. Other areas for further research are mentioned at the end of the document.2

Official figures are used to the extent that they are publicly available. An important aspect that prevents an exhaustive evaluation of the oil sector in Venezuela is the lack of available information regarding key performance indicators affecting the cost structure of oil projects, the cash flow of PDVSA, and the fiscal contributions of the oil sector to the government, among other important variables. Thus, on occasion, estimations for variables of interest and explanations for their divergence from official figures are provided.

The paper has two main sections. The first one analyzes the issues affecting the cash flow of PDVSA, the effects of macroeconomic and fiscal variables on both revenues and costs, as well as other financial issues affecting the performance of the company. The second section discusses some of the operational challenges facing the industry and mentions areas for further research.

Hausmann, R., Obach, J. & Santos, M.A., 2016. Special Economic Zones in Panama: Technology Spillovers from a Labor Market Perspective.Abstract

Special Economic Zones (SEZ) have played an important role in Panama's successful growth story over the previous decade. SEZ have attracted local and foreign investment by leveraging a business-friendly environment of low transaction costs, and created many stable, well-paid jobs for Panamanians. Beyond that, SEZ shall be assessed as place-based policy by their capacity to boost structural transformations, namely attracting new skills and more complex know-how not to be found in the domestic economy.

The aim of this paper is to evaluate the three largest SEZ in Panama:

  • Colon Free Zone
  • Panama-Pacific
  • City of Knowledge

Our results suggest that SEZ have been successful as measured by static indicators, such as foreign investment, job creation and productivity. We also find that SEZ have boosted inflows of high-skill immigrants, who are most likely generating positive knowledge spillovers on Panamanians productivity and wages. However, significant legal instruments and institutional designs are preventing Panama from taking full advantage of the skill variety hosted at the SEZ. Complex immigration processes inhibiting foreigners from transitioning out of the SEZ, a long list of restricted professions and even citizenships considered as a national security concern, are hindering the flow of knowledge, keeping the benefits coming from more complex multinational companies locked inside the gates of SEZ.

Hausmann, R., Morales, J.R. & Santos, M.A., 2016. Panama beyond the Canal: Using Technological Proximities to Identify Opportunities for Productive Diversification.Abstract

The economy of Panama has thrived for more than a decade, based on a modern service sector on the activities surrounding the Canal. Panama has inserted its economy into global value chains, providing competitive services in logistics, ship handling, financial intermediation, insurance, communication and trade. The expansion of the modern service sector required significant non-residential construction, including office buildings, commercial outlets, warehouses, and even shopping malls. Large public infrastructure projects such as the expansion of the Canal, the Metro, and Tocumen airport, have provided an additional drive and paved the road for productive diversification. But productive diversification does not spread randomly. A country diversifies towards activities that demand similar capacities than the ones already in place. Current capabilities and know-how can be recombined and redeployed into new, adjacent activities, of higher value added.

This report identifies productive capabilities already in place in Panama, as signaled by the variety and ubiquity of products and services that is already able to manufacture and provide competitively. Once there, we move on to identifying opportunities for productive diversification based on technological proximity. As a result, we provide a roadmap for potential diversification opportunities both at the national and sub-national level.

Hausmann, R., Espinoza, L. & Santos, M.A., 2016. Shifting Gears: A Growth Diagnostic of Panama.Abstract

Panama has been one of the fastest growing economies in the world over the previous decade. Growth has been spearheaded by the development of a modern service sector on the activities surrounding the Canal, and non-residential construction. Large public infrastructure projects and the private provision for infrastructure demanded by the service sector, have fueled growth and created a vibrant labor market for non-skilled workers.

Two warning signals hover over Panama´s stellar performance. The construction sector has been growing for a decade at a rate that is equivalent to doubling its stock of structures every four years. The demand for non-residential construction cannot grow indefinitely at a higher rate than the rest of the economy. This feeds into the second signal: Income inequality. In spite of the minor improvements registered over the accelerated-growth spell, Panama remains amongst the world´s top five most unequal countries.

Both warning signals point out to the need of further diversifying the Panamanian economy, and promoting economic activity in the provinces so as to deconcentrate growth and make it more inclusive.

We deployed our Growth Diagnostic methodology in order to identify potential binding constraints to that process. Skilled labor, necessary to gradually diversify into more complex and high value-added activities, is relatively scarce. This scarcity manifests into large wage-premiums to foreigners across all occupations, which are particular large within more complex industries.

Major investments in education have improved indicators of schooling quantitatively, but quality remains a major concern. We find that Panama’s immigration policies are preventing skills from spilling over from their special economic zones into the rest of the economy. On top of that, the list of professions restricted to Panamanians and other constraints on skilled labor flows, are constraining even further the pool of skills. As we document here, these efforts are not helping the Panamanian workers, quite the contrary.

We also find that corruption, and to a lesser extent, red tape, are other important factors that shall be addressed in order to allow Panama to shift the gears of growth, tackle inequality and continue growing at a fast pace.

Obuchi, R., Lira, B. & Raguá, D., 2016. Microeconomic binding constraints on private investment and growth in Venezuela A. Guerra, ed.,Abstract

Venezuela’s business environment is systematically evaluated as one of the worst in the world. Producing and investing in the country imposes costs and risks arising from macroeconomic instability. Beyond the problems of inflation, fiscal deficit and trade balance; firms and entrepreneurs also face enormous difficulties and discouragement going from the uncertainty about property rights to lack of electricity. To identify binding microeconomic constraints for investment in Venezuela, we reviewed international rankings and experiences about key elements of the business environment and conducted interviews with members of guilds and managers at large companies in the country. We find that the most biding constraints to investment are within the functioning of institutions, including weak property rights, and arbitrary, unbalanced and unpredictable enforcement of the law. Also binding is the flawed functioning of markets, including access to inputs and price controls.

España, L.P., Morales, J.R. & Barrios, D., 2016. Poverty, coverage of the Missions and social protection needs for the economic reform of Venezuela.Abstract

Even before the oil price crisis began in 2014, progress in reducing poverty in Venezuela had ceased and official figures showed that. According to the INE, between 2008 and 2013, the percentage of the population living in poverty remained almost the same, going from 33.1% to 34.2%.

Estas son las últimas cifras oficiales de pobreza de ingreso que disponemos ya que la última contabilización oficial de porcentaje de población en situación de pobreza es la del segundo semestre de 2013[1]. A partir de ese momento la descripción social de la pobreza en Venezuela ha dependido de estudios independientes realizados entre otros, por un consorcio de varias universidades del país[2] que dan cuenta de la evolución de la pobreza entre 2014 y 2015 (ENCOVI, 2014 y 2015), años donde se precipitaron los precios del petróleo hasta un tercio de lo que llegaron a ser durante 2008 acelerando un proceso de deterioro en los indicadores de desempeño económico y bienestar del hogar.

Según estas fuentes independientes de información la pobreza de ingresos en Venezuela habría llegado hasta un 55% en 2014 y 76% en 2015. Cifras que por sí solas hablan de la necesidad diseñar un plan de reformas económicas y sociales para hacerle frente al impacto social de la caída de los precios del petróleo, así como al conjunto de factores, más allá de los precios del crudo, que han llevado al país a tres años continuos de recesión y aumento de la pobreza.

En atención a lo anterior, el presente trabajo se enmarca dentro del conjunto de ejercicios de investigación que son necesarios para poder diseñar un programa de estabilización económica y su correspondiente plan de protección social. En ese sentido, en lo que sigue trataremos de dimensionar el número de familias que necesitarían formar parte de este potencial plan de protección social.

Para ello nos valdremos como fuente de información de la ENCOVI 2014 y 2015, encuestas desde las cuales no sólo tenemos información para contabilizar los hogares e individuos en estado de necesidad, sino además las coberturas probables de los programas sociales (Misiones) que actualmente implementa el gobierno de Venezuela, para de esta forma estimar; en primer lugar, las familias en situación de pobreza que reciben beneficios sociales; en segundo lugar las que estando en esa condición de pobreza no los reciben y; por último, y con miras a la reforma de los programas y la introducción de elementos de progresividad distributiva, los beneficiarios que aún sin ser población objetivo, por no estar en situación de pobreza, son receptores de transferencias, pensiones o becas por parte del Estado.

Adicionalmente a lo anterior, las políticas de control de cambio y la regulación de los precios, aunado a los problemas de abastecimiento, han hecho que los precios de los bienes a los que tienen acceso los distintos grupos sociales varían según si se adquieren en los mercados controlados o en los informales. Estos diferenciales de precios son muy importantes y están generando impactos distributivos difíciles de estimar, pero fundamentales para entender las necesidades de protección social que requieren los hogares para cubrir la canasta de productos básicos.

Es por ello que este trabajo también se propone describir a muy alto nivel los problemas distributivos generados por los diferenciales de precios. Si bien probablemente no sea posible llegar a conclusiones definitivas, al menos plantearemos lo relevante del tema para entender como la escasez de productos y las regulaciones de precios han introducido un conjunto de distorsiones en los precios y en el acceso a los bienes esenciales y presentaremos algunos de los dilemas y preguntas que estas distorsiones generan al momento de analizar la capacidad de satisfacer necesidades básicas en Venezuela.

[1] En Agosto de 2016, el Instituto Nacional de Estadística (INE) publicó estadísticas sobre el porcentaje de hogares en situación de pobreza por primera vez desde el año 2013. La serie fue actualizada para incluir los datos de 2014 y el primer semestre de 2015. Para el primer semestre de 2014 la cifra de hogares en situación de pobreza por ingreso alcanzó 29,5%, para el segundo semestre de ese año llegó a 32,6% y finalmente para el primer semestre de 2015 33,1% de los hogares se encontraban en situación de pobreza por ingresos. Sin embargo, el INE no ha hecho públicas ni el valor de Canasta Alimentaria Normativa para 2015, ni las Encuestas de Hogares que sustentan este cálculo ni las cifras de pobreza por ingreso como porcentaje de la población.

Russell, S., Barrios, D. & Andrews, M., 2016. Getting the Ball Rolling: Basis for Assessing the Sports Economy.Abstract

Data on the sports economy is often difficult to interpret, far from transparent, or simply unavailable. Data fraught with weaknesses causes observers of the sports economy to account for the sector differently, rendering their analyses difficult to compare or causing them to simply disagree. Such disagreement means that claims regarding the economic spillovers of the industry can be easily manipulated or exaggerated. Thoroughly accounting for the industry is therefore an important initial step in assessing the economic importance of sports-related activities. For instance, what do policymakers mean when they discuss sports-related economic activities? What activities are considered part of the "sports economy?" What are the difficulties associated with accounting for these activities? Answering these basic questions allows governments to improve their policies.

The paper below assesses existing attempts to understand the sports economy and proposes a more nuanced way to consider the industry. Section 1 provides a brief overview of existing accounts of the sports economy. We first differentiate between three types of assessments: market research accounts conducted by consulting groups, academic accounts written by scholars, and structural accounts initiated primarily by national statistical agencies. We then discuss the European Union’s (EU) recent work to better account for and understand the sports economy. Section 2 describes the challenges constraining existing accounts of the sports economy. We describe two major constraints - measurement challenges and definition challenges - and highlight how the EU's work has attempted to address them. We conclude that, although the Vilnius Definition improves upon previous accounts, it still features areas for improvement.

Section 3 therefore proposes a paradigm shift with respect to how we understand the sports economy. Instead of primarily inquiring about the size of the sports economy, the approach recognizes the diversity of sports-related economic activities and of relevant dimensions of analysis. It therefore warns against attempts at aggregation before there are better data and more widely agreed upon definitions of the sports economy. It asks the following questions: How different are sports-related sectors? Are fitness facilities, for instance, comparable to professional sports clubs in terms of their production scheme and type of employment? Should they be understood together or treated separately? We briefly explore difference in sports-related industry classifications using data from the Netherlands, Mexico, and the United States. Finally, in a short conclusion, we discuss how these differences could be more fully explored in the future, especially if improvements are made with respect to data disaggregation and standardization.

Santos, M.A., 2015. The Right Fit for the Wrong Reasons: Real Business Cycle in an Oil-Dependent Economy.Abstract

Venezuela is an oil-dependent economy subject to large exogenous shocks, with a rigid labor market. These features go straight at the heart of two weaknesses of real business cycle (RBC) theory widely reported in the literature: Neither shocks are volatile enough nor real salaries are sufficiently flexible as required by the RBC framework to replicate the behavior of the economy. We calibrate a basic RBC model and compare a set of relevant statistics from RBC-simulated time series with actual data for Venezuela and the benchmark case of the United States (1950-2008). In spite of Venezuela being one of the most heavily intervened economies in the world, RBC-simulated series provide a surprisingly good fit when it comes to the non-oil sector of the economy, and in particular for labor markets. Large restrictions on dismissal and widespread minimum (nominal) wage put all the burden of adjustment on prices; which translate into highly volatile real wages.

In this document we describe the size of the Poblacion Flotante of
Bogota (D.C.). The Poblacion Flotante is composed by people who live
outside Bogota (D.C.), but who rely on the city for performing their job.
We estimate the Poblacion Flotante impact relying on a new data source
provided by telecommunications operators in Colombia, which enables us
to estimate how many people commute daily from every municipality of
Colombia to a specic area of Bogota (D.C.). We estimate that the size of
the Poblacion Flotante could represent a 5.4% increase of Bogota (D.C.)'s
population. During weekdays, the commuters tend to visit the city center
more.

Gomez-Lievano, A., Tellez, J. & Lora, E., 2015. New Insights About Wage Inequality in Colombia.Abstract

This paper presents a descriptive analysis of wage inequality in Colombia by cities and industries and attempts to evaluate the impact of the inequality of industries on inequality of cities. Using the 2010-2014 Colombian Social Security data, we calculate the gini coefficient for cities and industries and draw comparisons between their distributions. Our results show that while cities are unequal in similar ways, industries differ widely on how unequal they can be with ginis. Moreover, industrial structure plays a significant role to determine city inequality. Industrial framework proves to be a key element in this area for researches and policymakers.

Evidence That Calls-Based and Mobility Networks Are Isomorphic
Coscia, M. & Hausmann, R., 2015. Evidence That Calls-Based and Mobility Networks Are Isomorphic. PLOS One , 10. Publisher's VersionAbstract

Social relations involve both face-to-face interaction as well as telecommunications. We can observe the geography of phone calls and of the mobility of cell phones in space. These two phenomena can be described as networks of connections between different points in space. We use a dataset that includes billions of phone calls made in Colombia during a six-month period. We draw the two networks and find that the call-based network resembles a higher order aggregation of the mobility network and that both are isomorphic except for a higher spatial decay coefficient of the mobility network relative to the call-based network: when we discount distance effects on the call connections with the same decay observed for mobility connections, the two networks are virtually indistinguishable.

Reinhart, C. & Santos, M.A., 2015. From Financial Repression to External Distress: The Case of Venezuela.Abstract

Recent work has supported that there is a connection between domestic debt level and sovereign default on external debt. We examine the potential linkages in a case study of Venezuela from 1984 to 2013. This unique example encompasses multiple financial crises, cycles of liberalization and policy reversals, and alternative exchange rate arrangements. The Venezuelan experience reveals a nexus among domestic debt, financial repression, and external vulnerability. Unlike foreign currency-denominated debt, debt in domestic currency may be reduced through financial repression, a tax on bondholders and savers producing negative real interest rates. Using a variety of methodologies we estimate the magnitude of the tax from financial repression. On average, this financial repression tax (as a share of GDP) is similar to those of OECD economies, in spite of much higher domestic debt-to-GDP ratios in the latter. The financial repression "tax rate" is significantly higher in years of exchange controls and legislated interest rate ceilings. In line with earlier literature on capital controls, our comprehensive measures of capital flight document a link between domestic disequilibrium and a weakening of the net foreign asset position via private capital flight. We suggest these findings are not unique to the Venezuelan case.
