This paper derives consistent standard errors for a panel Tobit model in the presence of correlated errors. The problem is framed in the context of Newey and West (1987), considering the Tobit model as a special case of a GMM estimator. JEL codes: C23, C24

This paper shows how the productive interplay of theory and experimental work has furthered our understanding of credit markets in developing countries. Descriptive facts motivated a body of theory, which in turned motivated experiments designed to test it. Results from these experiments reveal both the success and the limits of the theory, prompting new work to refine it. We argue that the lit...

This paper provides evidence that domestic opportunities to share risk have contributed to lower rates of private saving. Two econometric procedures are used in the analysis: (1) traditional instrumental variables estimation and (2) dynamic panel methods. The results reveal a negative relationship between domestic opportunities to diversify risk and aggregate private saving rates in a cross-sec...

This paper extends the model of Fielding (1999), which is designed to explain changes in investment in South Africa during the Apartheid period, by allowing a role for indicators of political instability and political and civil rights, as measured by Fedderke et al. (1999). The conclusions based on estimation of the original model are robust to the inclusion of the political factors, but these ...

We examine the match/mismatch between demand and supply of impact investments. show that some geographic regions display an upward match, while others exhibit a downward match. explain how with well-developed (or less-developed) economies are not necessarily equal to investment markets. also highlight sectors exhibiting match or mismatch investments, potential reasons. Regarding both sector con...

We estimate the political economy determinants of budget deficit forecast errors. Since the adoption of the Stability Pact, Eurozone governments have manipulated forecasts before elections. The political orientation and the institutional design of governments also affects the quality of forecasts. JEL classifications: H62, H87, C23, C53, E62

This study analyzes the existence of a complementary relationship between public and private spending on Research and Development activities. The results show that public funding does not produce a substitution effect on private spending. In fact, depending on the methodology used, public subsidies actually produce a crowding in effect of up to 49% on private spending. JEL: C23; L11;
