Equity premium in a production economy: A parametric example

A simple Arrow-Debreu model with production and adjustment cost is developed and it is shown how the production parameters interact in determining the steady state equity premium. We also show that the equity premium is highest in exchange economy.     

On the first passage time processes of brownian motion with positive drift

Abstract

The first passage time processes of Brownian Motion with positive drift are of considerable importance, particularly in life-testing or life-time situation as a natural consequence. It has been used in sequential analysis, e.g. finding the best test for testing the hypothesis of no drift versus the alternative of positive drift in a Brownian Motion. Various properties of the first passage time process of Brownian Motion with positive drift are reviewed and several new properties are investigated. In short, γ-variation properties, characterization, and behaviour at infinity are discussed.     

MARX‐BIASED TECHNICAL CHANGE AND THE NEOCLASSICAL VIEW OF INCOME DISTRIBUTION

This paper empirically tests two competing views about capital–labour substitution at the aggregate level in capitalist economies: the classical model with Marx‐biased technical change versus the neoclassical model. Following Foley and Michl (1999 ), the classical viability condition of technical change is used to draw out two different hypotheses about the profit share in national income corresponding to the two competing models. A stochastic version of the viability condition is empirically tested with data from the Extended Penn World Tables 2.1 using a simple cross‐country estimation strategy. It is found that the data overwhelmingly rejects the neoclassical theory.     

Information and Communications Technology as a General-Purpose Technology: Evidence from US Industry Data

Abstract. Many people point to information and communications technology (ICT) as the key for understanding the acceleration in productivity in the United States since the mid-1990s. Stories of ICT as a 'general-purpose technology' suggest that measured total factor productivity (TFP) should rise in ICT-using sectors (reflecting either unobserved accumulation of intangible organizational capital; spillovers; or both), but with a long lag. Contemporaneously, however, investments in ICT may be associated with lower TFP as resources are diverted to reorganization and learning. We find that US industry results are consistent with general-purpose technology (GPT) stories: the acceleration after the mid-1990s was broad-based – located primarily in ICT-using industries rather than ICT-producing industries. Furthermore, industry TFP accelerations in the 2000s are positively correlated with (appropriately weighted) industry ICT capital growth in the 1990s. Indeed, as GPT stories would suggest, after controlling for past ICT investment, industry TFP accelerations are negatively correlated with increases in ICT usage in the 2000s.
