In this paper we consider the problem of making inference on a structural parameter in instrumental variables regression when the instruments are only weakly correlated with the endogenous explanatory variables. Adopting a local-to-zero assumption as in Staiger and Stock (1994) on the...

In this paper, we propose methods of the determination of the rank of matrix. We consider a rank test for an unobserved matrix for which an estimate exists having normal asymptotic distribution of order N1/2 where N is the sample size. The test statistic is based on the smallest estimated...

This paper explores the connection between unemployment and subjective well-being in Finland by using cross-sections for the years 1990, 1996 and 2000 from World Values Surveys. An unprecedented increase in the national unemployment rate (from 3 to 17 per cent) did not produce a drop in the mean...

The debate on the relationship between environmental regulation and competitiveness has been a topic of discussion for a number of years now. As early as 1991, the American economist Michael E. Porter proposed that stringent environmental regulation (under the condition that it is efficient) can...

THIS PAPER DERIVES AND ESTIMATES A BARRO-TYPE REDUCED-FORM EQUATION FOR DOMESTIC REAL OUTPUT FROM A SIMPLE STRUCTURAL MODEL OF AN OPEN DEVELOPING ECONOMY IN WHICH MARKETS CLEAR CONTINUOUSLY AND EXPECTATIONS ARE RATIONAL. THE FORM IN WHICH OPEN ECONOMY VARIABLES APPEARED WAS EXPLICITLY DERIVED...

Most prices and interest rates display fluctuating levels that embody extractable energy and equivalent amounts of money. Such fluctuations are also associated with varying degrees of uncertainty. Shannon's derivations of spectral entropy and information content offer computational techniques...

We consider mean-reverting stochastic processes and build a self- consistent model for forward price dynamics and their applications in power industries. This model with stochastic volatility of the forward price is built using the ideas and equations of stochastic differential geometry in order...

We investigate confidence intervals and inference for the instrumental variables model with weak instruments. Wald-based confidence intervals perform poorly in that the probability they reject the null is far greater than their nominal size. In the worst case, Wald-based confidence intervals...

This paper analyzes the systematic relationship between the stock market valuations, the nominal GDPs and the interest rates of six Asian countries, using not 'single equation regression,' but an alternative methodology based on complete, multidirectional, least squares projections. We compare...

In spite of elaborate descriptive and correlational studies, the most ubiquitous phenomenon in economics, namely inflation, has remained unexplained in terms of its mathematical origins. Keynes had attempted to relate inflation to a mechanism of "sticky wages and prices". Hitherto, such theories...
