model of the type used to forecast the effects on an industry of changes in the national economy is described. The components representing input data and the type of output from such a model are discussed. This paper is intended as a tutorial discussion of an advanced application in data processing. Input-output models are used to forecast various effects that can occur to an industry as it int...

This paper characterizes the dynamic effects of shocks in government spending and taxes on economic activity in the United States in the postwar period. It does so by using a structural VAR approach that relies on institutional information about the tax and transfer systems and the timing of tax collections to identify the automatic response of taxes and spending to activity, and, by implicatio...

This paper provides a generic, very fast method for computing exact density ratio class bounds on posterior expectations, given the output of a posterior simulator. It illustrates application of the method in an econometric model of typical complexity. In this model, the exact bounds for expectations of some functions of interest are well approximated by the established asymptotic approximation...

In this paper I propose an alternative to calibration of linearized singular dynamic stochastic general equilibrium models. Given an a-theoretical econometric model as a representative of the data generating process, I will construct an information measure which compares the conditional distribution of the econometric model variables with the corresponding singular conditional distribution of t...

This paper examines the rationale underlying periodic price promotions, or sales, for perishable food products by supermarket retailers. Whereas previous studies explain sales in a single-product context as arising from informational, storage cost, or demand heterogeneity, this study focuses on the central role of retailers as multi-product sellers of complementary goods. By offering a larger n...

We examine the crucial policy question of whether the South African (SA) stock market values a dual board leadership structure (DBLS) using a sample of 169 listed firms from 2002 to 2007. We find a significant positive link between DBLS and market valuation, but only in firms with independent chairpersons, implying that the market values firms with independent DBLS more highly. Our results are ...

In order to explore how Web search volume dynamically influences product sales during the whole product life cycle, this paper collects Web search volume and sales data of movies and does an empirical analysis using econometric models. The empirical results show that Web search volume before the launch of a new product has a positive impact on the product sales in the initial period of introduc...

Irrigation is one means by which agricultural production can be increased to meet the growing food demands in the world. This study evaluated the effect of small-scale irrigation on farm household income in production. The specific objective of this study is to identify the factors influencing participation in small-scale irrigation and provides bases for policy makers in Girawa district, Easte...
