Export Dynamics in Colombia: Firm-Level Evidence

Using transactions-level customs data from Colombia, we study firm-specific export patterns over the period 1996-2005. Our data allow us to track firms entry and exit into and out of individual destination markets, as well as their revenues from selling there. We find that, in a typical year, nearly half of all Colombian exporters were not exporters in the previous year. These new exporters tend to be extremely small in terms of their overall contribution to export revenues, and most do not continue exporting in the following year. Hence export sales are dominated by a small number of very large and stable exporters. Nonetheless, out of each cohort of new exporters, a fraction of firms go on to expand their foreign sales very rapidly, and over the period of less than a decade, these successful new exporters account for almost half of total export expansion. Finally, we find that new exporters begin in a single foreign market and, if they survive, gradually expand into additional destinations. The geographic expansion paths they follow, and their likelihood of survival as exporters, depend on their initial destination market.

Labor Market Effects of Payroll Taxes in Developing Countries: Evidence from Colombia

We use a panel of manufacturing plants from Colombia to analyze how the rise in payroll tax rates over the 1980s and 1990s affected the labor market. Our estimates indicate that formal wages fall by between 1.4% and 2.3% as a result of a 10% rise in payroll taxes. This “less‐than‐full shifting” is likely to be the result of weak linkages between benefits and taxes and the presence of downward wage rigidities in Colombia. Because the costs of taxation are only partly shifted from employers to employees, employment also falls. Our results indicate that a 10% increase in payroll taxes lowered formal employment by between 4% and 5%. In addition, we find some evidence of less shifting and larger disemployment effects for production than for nonproduction workers. These results suggest that policies aimed at boosting the relative demand of less skilled workers by reducing social security taxes may be effective in Latin American countries, where minimum wages bind and benefits are often not directly linked to contributions.

Factor Adjustments after Deregulation: Panel Evidence from Colombian Plants

We analyze nonlinear adjustments of capital and labor using plant data from the Colombian Annual Manufacturing Survey, allowing for interdependence in adjustments of the two factors. We find nonlinear employment and capital adjustments. We also find that capital shortages reduce hiring, and labor surpluses reduce capital shedding. Moreover, we find that job destruction and capital formation increased after factor market deregulation in Colombia. Finally, we find that completely eliminating frictions in factor adjustment would yield a substantial increase in aggregate productivity through improved allocative efficiency, but that the actual impact of the Colombian deregulation on productivity was modest.

Migration and Cross-Border Financial Flows

Migration facilitates the flow of information between countries, thereby reducing informational frictions that potentially hamper cross-country financial flows. Using a gravity model, migration is found to be highly correlated with financial flows from the migrants host country to her home country. The correlation is strongest where information problems are more acute (e.g., between culturally more distant countries), for asset types that are more informational sensitive, and for the type of migrants that are most able to enhance the flow of information on their home countries, namely, skilled migrants. These differential effects are interpreted as evidence for the role of migration in reducing information frictions between countries.
