This paper investigates whether convenience yield is an important factor in determining optimal decisions for a forestry investment. The Kalman filter method is used to estimate three different models of lumber prices: a mean reverting model, a simple geometric Brownian motion and the two-factor...

This paper extends the generalized empirical likelihood method to the case in which the moment conditions are defined on a continuum (CGEL). We show, for the iid case, that CGEL is asymptotically equivalent at the first order to the generalized method of moments for a continuum (CGMM) developed...

To comply with laws, regulations and social demands, polluting firms increasingly purchase the needed means from specialized suppliers. This paper an- alyzes this relatively recent phenomenon. We show how environmental regulation, the size of the output market, the elasticity of demand for...

A leading explanation of long run U.S. inflation trends attributes both the fall of inflation in the 1980s and the subsequent years of low and stable inflation to well run monetary policy pinning down inflationary expectations. Most other OECD economies experienced a similar rise and fall of...
