Recent empirical results about the US term structure are difficult to reconcile with the classical hypothesis of rational expectations even if time-varying but stationary term premia are allowed for. A hypothesis of rational learning about the conditional variance of the log pricing kernel is...

The paper uses the 1992 household survey for Bulgaria to show poor revenue performance of the income tax structure prevailing in 1992, which did not take into account the underlying distribution of income. The paper shows that Bulgaria can benefit from a much lower and simpler income tax rate...

Meeting government revenue needs without inhibiting private sector development is a key challenge of tax policy during the transition from the socialist system. The paper explores issues in the design of tax bases and tax structures in the transition and argues that transition economies would...

The note documents and discusses the modalities and consequences of the phenomenon of siphoning profits of state enterprises for private uses by state enteprise managers and insiders in Bulgaria during the period of early transition.

This is an Invited paper for the World Congress of the Econometric Society held in Seattle in August 2000. We discuss the strong connections between auction theory and "standard" economic theory, and argue that auction-theoretic tools and intuitions can provide useful arguments and insights in a...

This paper analyses the problem of natural resource scarcity and its implications for economic development and international cooperation. We examine the meaning and measurement of resource “scarcity” and its implications for economic growth and development. The paper describes the conditions...

This study uses an agent-based computational labor market framework to experimentally study the relationship between job capacity, job concentration, and market power. Job capacity is measured by the ratio of potential job openings to potential work offers, and job concentration is measured by...

This study undertakes a systematic experimental investigation of hysteresis (path dependency) in an agent-based computational labor market framework. It is shown that capacity asymmetries between work suppliers and employers can result in two distinct hysteresis effects, network and behavioral,...

This study presents, motivates, and illustrates the use of a computational laboratory for the investigation of evolutionary trade network formation among strategically interacting buyers, sellers, and dealers. The computational laboratory, referred to as the Trade Network Game Laboratory (TNG...

We model a homogeneous product environment where identical e-retailers endogenously engage in both brand advertising (to create loyal customers) and price advertising (to attract 'shoppers'). Our analysis allows for 'cross-channel' effects; indeed, we show that price advertising is a substitute...
