Ineffective Controls on Capital Inflows under Sophisticated Financial Markets: Brazil in the Nineties. Textos para discusso 516, Department of Economics PUC-Rio

We analyze the Brazilian experience in the 1990s to assess the effectiveness of controls on capital inflows in restricting financial inflows and changing their composition towards long term flows. Econometric exercises (VARs) showed that controls on capital inflows were effective in deterring financial inflows for only a brief period, from two to six months.

The main conclusion is that controls on capital inflows, while they may be desirable, are of very limited effectiveness under sophisticated financial markets. Resumo: Analisamos neste artigo a eficácia dos controles de entrada de capitais em restringir e selecionar os influxos financeiros. A partir de estimações de VARs, concluímos que no
