Capital flows and monetary control under a domestic currency substitution regime: the recent Brazilian experience

The 90s have witnessed a resumption in capital flows to Latin America. due to the conjugation of low interest rates in the US and economic reforms in most LA countries. In Brazil. however. substantial capital flows have becn induced by the extremely high domestic interest rates practiced by the Central Bank as a measure of last reson given the absence of successful stabilization policies. These very high interest rates were needed to prevent capital flight in a context of a surprisingly stable inflation rate above 20% a month. and keep interest bearing govemment securities preferable to foreign assets as money substitutes. We carefully describe how this domestic currency substitution regime (interest bearing govemment securities are substituted for MIas cash holdings) requires the Central Bank to renounce aoy control over monerary aggregates. In this domestic currency substitution regime. hyperinflation is the most likely outcome of an isolated (i.e.. without fiscal adjusanents) attempt by the Brazilian Central Bank to control money.

Elasticity of substitution between capital and labor: a panel data approach

This paper estimates the elasticity of substitution of an aggregate production function. The estimating equation is derived from the steady state of a neoclassical growth model. The data comes from the PWT in which different countries face different relative prices of the investment good and exhibit different investment-output ratios. Then, using this variation we estimate the elasticity of substitution. The novelty of our approach is that we use dynamic panel data techniques, which allow us to distinguish between the short and the long run elasticity and handle a host of econometric and substantive issues. In particular we accommodate the possibility that different countries have different total factor productivities and other country specific effects and that such effects are correlated with the regressors. We also accommodate the possibility that the regressors are correlated with the error terms and that shocks to regressors are manifested in future periods. Taking all this into account our estimation resuIts suggest that the Iong run eIasticity of substitution is 0.7, which is Iower than the eIasticity that had been used in previous macro-deveIopment exercises. We show that this lower eIasticity reinforces the power of the neoclassical mo deI to expIain income differences across countries as coming from differential distortions.

Import substitution and economic growth

In spite of Latin America s dismal economic performance between the 1950s and 1980s, the region experienced strong capital deepening. Furthermore, pro- ductivity (measured as TFP) grew at low rates in comparison with the U.S. In this paper, we suggest that all these facts can be explained as a consequence of the restrictive trade regime adopted at that time. Our analytical framework is based on a dynamic Heckscher-Ohlin model, with scale economies in the capital- intensive sector. We assume an economy that is initially open and specialized in the production of labor-intensive goods. The trade regime is modeled as a move to a closed economy. The model produces results consistent with the Latin American experience. Speci cally, for a su¢ ciently small country, there will be no long-run growth in income per capita, but capital per capita will increase. As a result, measured TFP will fall.
