We develop a simple model to analyse the ‘dual-track’ approach to transition to a market economy as a mechanism for implementing efficient Pareto-improving economic reform, that is, reform achieving efficiency without creating losers. The approach, based on the continued enforcement of the...

We introduce labour market imperfections (i.e. unions and the existence of a wage floor) in a finance-constrained monetary economy with heterogenous agents and increasing returns to scale due to labour and capital productive externalities. We find that indeterminacy emerges for empirically...

I present a simple model in which it is possible that opening a new market makes everybody worse off. Unlike previous examples in the literature, the analysis does not rely on relative price changes of different consumption goods. This is shown in a standard framework in which uninformed traders...

Agents from a homogeneous population organize themselves into productive partnerships and are confronted with a hold-up problem when making relation-specific investments in those partnerships. The problem is mitigated if agents can leave a partnership in which they have invested, bear the costs...

Recent empirical work finds that surprisingly little variation in the demand for insurance is explained by heterogeneity in risks. I distinguish between heterogeneity in risk preferences and risk perceptions underlying the unexplained variation. Heterogeneous risk perceptions induce a systematic...

The paper proposes a general model that will encompass trade and social benefits of a common language, a preference for a variety of languages, the fundamental role of translators, an emotional attachment to maternal language, and the threat that globalization poses to the vast majority of...

Limited consumer attention limits product market competition: prices are stochastically lower the more attention is paid. Ads compete to be the lowest price with other ads from the same sector and they compete for attention with ads from other sectors: equilibrium sector ad shares under free...

Digital goods are bit strings, sequences of 0s and 1s, that have economic value. They are distinguished from other goods by five characteristics: digital goods are non-rival, infinitely expansible, discrete, aspatial, and recombinant. The New Economy is one where the economics of digital goods...

We discuss the effects of unions in the labour market on steady-state multiplicity and welfare, and on the occurrence of local indeterminacy, local bifurcations and (stochastic and deterministic) endogenous fluctuations driven by self-fulfilling expectations. We consider an overlapping...

This paper examines the long-run effects of growth on unemployment. It assumes that growth arises explicitly from the introduction of new technologies, which require labour re-allocation for their implementation. Using a variant of the search theory developed by Pissarides, the paper shows how...
