Political Economy of the Web

Slides to introduce political economy, and its relevance to the study of the Web. Brief review of methods and issues.

Labor supply, biased technological change and economic growth

Se utiliza un modelo de innovaciones sesgadas para estudiar los efectos de cambios exógenos en la oferta laboral. En un contexto de innovaciones sesgadas, a medida que las economías acumulan capital, el trabajo se hace relativamente más escaso y más caro, por este motivo, hay incentivos para adoptar tecnologías ahorradoras de trabajo. Del mismo modo un cambio en la oferta laboral afecta la abundancia de factores y sus precios relativos. En general, una reducción de la oferta laboral, hace que el trabajo sea más caro y genera incentivos para cambio tecnológico ahorrador de trabajo. Así, el efecto inicial que tiene el cambio en la oferta laboral sobre los precios de los factores es mitigado por el cambio tecnológico. Finalmente, los movimientos en la remuneración a los factores afectan las decisiones de ahorro y, por lo tanto, la dinámica del crecimiento. En este trabajo se exploran las consecuencias de una reducción de la oferta laboral en dos contextos teóricos diferentes: un modelo de agentes homogéneos y horizonte infinito y un modelo de generaciones traslapadas.

The international economic crisis and the colombian economy

The purpose of this research is to provide an approximation to the likely effects of the crisis on the Colombian economy and to the effectiveness of policy response. For this, the most relevant transmission channels and policy measures are simulated in the setting of a static computable general equilibrium model (CGE). The results obtained are interesting in their own right and are in line with what could be expected given the information available on the behavior of the Colombian economy. Furthermore, they call into question the effectiveness of governmental intervention as judged by its intended countercyclical effects.

Economic shocks and crime: evidence from the crash of ponzi schemes

In November 2008, Colombian authorities dismantled a network of Ponzi schemes, making hundreds of thousands of investors lose tens of millions of dollars throughout the country. Using original data on the geographical incidence of the Ponzi schemes, this paper estimates the impact of their break down on crime. We find that the crash of Ponzi schemes differentially exacerbated crime in affected districts. Confirming the intuition of the standard economic model of crime, this effect is only present in places with relatively weak judicial and law enforcement institutions, and with little access to consumption smoothing mechanisms such as microcredit. In addition, we show that, with the exception of economically-motivated felonies such as robbery, violent crime is not affected by the negative shock.

The political economy of bovine tuberculosis in Great Britain

A brief history of bovine tuberculosis (bTB) and its control in Great Britain is presented. Numerous diverse policies to control the disease in man, cattle and wildlife have been pursued over the last 100 years and many millions of pounds have been spent. After notable success in reducing the incidence and prevalence of bTB in cattle in GB from the 1950s to the mid-1980s, the number of cattle slaughtered has increased with increased geographical spread continually since that time with a high point of bTB incidence in 2008. This increase appeared to coincide with changing policy regarding the control of the disease in badgers with a more humane approach adopted and with strengthened protection for badgers through legislation. Indeed, much controversy has been involved in the debate on the role of badgers in disease transmission to cattle and the need for their control as vectors of the disease with various commissioned research projects, trials, public consultations and media attention. The findings of two social science investigations presented as examples showed that citizens generally believed that bTB in cattle is an important issue that needs to be tackled but objected to badgers being killed, whilst cattle farmers were willing to pay around £17/animal/year for a bTB cattle vaccine. It is noted that successes regarding the control of bTB in other countries have combined both cattle and wildlife controls and had strong involvement from industry working with government.

The political economy of exchange rate in Brazil

This paper reviews part of the political economy literature on exchange rate policy relevant to understanding the political motivations behind the Brazilian exchange rate policy. We shall first examine the distributive role of the exchange rate, and the way it unfolds in terms of the desired political goals. We will follow by analyzing exchange policy as indicative of government effciency prior to elections. Finally, we discuss fiscal policy from the point of view of political economy, in which the exchange rate results from the macroeconomic equilibrium. Over this review, the Brazilian exchange rate policy is discussed in light of the theories presented.

Constructing coincident and leading indices of economic activity for the brazilian economy

This paper has three original contributions. The first is the reconstruction effort of the series of employment and income to allow the creation of a new coincident index for the Brazilian economic activity. The second is the construction of a coincident index of the economic activity for Brazil, and from it, (re)establish a chronology of recessions in the recent past of the Brazilian economy. The coincident index follows the methodology proposed by TCB and it covers the period 1980:1 to 2007:11. The third is the construction and evaluation of many leading indicators of economic activity for Brazil which fills an important gap in the Brazilian Business Cycles literature.

The political economy of exchange rate policy in Brazil: 1964-1999

This paper was developed as part of a broader research program on the political economy of exchange rate policies in Latin America and the Caribbean. We are grateful for helpful comments and suggestions from Jeff Frieden, Ernesto Stein, Jorge Streb, Marcelo Neri and seminar participants at Getulio Vargas Foundation, PUC-Rio, IDB workshop on The Political Economy of Exchange Rate Policies in Latin America and the Caribbean, and LACEA meeting in Buenos Aires. We thank René Garcia for providing us with a Fortran program for estimating the Markov Switching Model, Ilan Goldfajn for sending us updated estimates of the real exchange rate series of Goldfajn and Valdés (1996), Altamir Lopes and Ricardo Markwald for kindly furnishing data on Brazilian external accounts, and Carla Bernardes, Gabriela Domingues, Juliana Pessoa de Araújo, and, specially, Marcelo Pinheiro for excellent research assistant. Both authors thank CNPq for a research fellowship.
