Full information maximum likelihood estimation of econometric models, linear and nonlinear in variables, is performed by means of two gradient algorithms, using either the Hessian matrix or a computationally simpler approximation. In the first part of the paper, the behavior of the two methods...

En el presente trabajo revisamos los principios de una popular estrategia de inversión basada en opciones financieras, en especial las opciones de venta (puts), y testeamos de manera estadística una estrategia de inversión basada en la compra venta de opciones de venta sobre un índice en el...

We provide a generalization of the Anderson-Rubin (AR) procedure for inference on parameters which represent the dependence between possibly endogenous explanatory variables and disturbances in a linear structural equation (endogeneity parameters). We focus on second-order dependence and stress...

Decision making can be a complex process requiring the integration of several attributes of choice options. Understanding the neural processes underlying (uncertain) investment decisions is an important topic in neuroeconomics. We analyzed functional magnetic resonance imaging (fMRI) data from...

Sustainable intensification of Ghana’s smallholder farming is critical to mitigate rural poverty. Innovations for sustainable intensification include agro-ecological practices, which build up soil fertility, and mulching, which conserves soil moisture. To stimulate the adoption of these...

The present study investigates the price dynamics of two agricultural commodities, pork and poultry, in order to determine whether there is a single or multiple markets within the EU. The investigation relies on the notion of a price club (meaning a group of countries in which prices obey the...

This paper investigates the long-run neutrality of money using quarterly data of South Korea and Taiwan and the methodology of King and Watson (1997) particular attention is given to the integration and cointegration properties of the variables. Empirical evidence provides considerable support...

This note studies the long-run relationship between real estate and stock markets in the Taiwan context over the 1986Q3 to 2006Q4 period, using standard cointegration test of Johansen and Juselius (1990) and that of Engle-Granger (1987) as well as the fractional cointegration test of Geweke and...

In this paper, we provide two empirical findings. First, exploring 140 monthly macroeconomic and financial variables and applying the principal components method, we find 12 static factors and 8 dynamic factors from 1959 to 2005 in the US. Second, we find the real factor and interest rate factor...
