In a two-type Stiglitz (1982) model of optimal non-linear taxation it is shown that when the utility function relating to consumption is logaritmic the shadow price of the incentive constraint relating to the optimal tax problem exactly equals the Gini coefficient of the secondbest optimal...

By considering firms operating in a perfectly- or monopolisticallycompetitive industry with free entry, we show that well-established results on the celebrated LeChatelier principle (LCP) do not extend into an endogenous competitive environment. For instance, labour demand may be more elastic in...

We augment the mechanism used in Nash implementation with a political process that collects the opinions of a subset of individuals with a xed probability distribution. The outcome is a function of only the collected opinions. We show that the necessary - and sometimes sufficient - condition for...

We study the effects of price-matching in a duopoly setting in which each firm selects both its price and output, simultaneously. We show that the availability of a pricematching option leads to the Cournot outcome in this setting. This result is a stark contrast to the one obtained in the...

This paper examines the relationship between employee turnover, HRM practices and innovation in Chinese firms in five high technology sectors. We estimate hurdle negative binomial models for count data on survey data allowing for analyses of the extensive as well as intensive margins of firms’...

Exploiting pre-intervention variation in flu/pneumonia, tuberculosis and maternal mortality, together with time variation arising from medical breakthroughs starting in the late 1930s, this paper studies the aggregate impact of large health shocks across US states. The analysis demonstrates that...

This paper studies the mechanism by which club memberships, activities, and rules are chosen in a decentralized economy. For this purpose, we develop a model of competing auctions for club goods. This is a dynamic game where each seller first chooses an auction format; next, each buyer chooses a...

A frequent criticism of unit root tests concerns the poor power and size properties that many of such tests exhibit. However, the past decade or so intensive research has been conducted to alleviate these problems and great advances have been made. The present paper provides a selective survey...

The authors have previously surveyed the AEL, aid (empirical) effectiveness literature, using the technique of meta-analysis. We reached the result that the small positive effect of aid on growth found in the average study is mostly a publication selection bias. This present study concentrates...

Economic research typically runs J regressions for each selected for publication – it is often selected as the ‘best’ of the regressions. The paper examines five possible meanings of the word ‘best’: SR0 is ideal selection with no bias; SR1 is polishing: selection by statistical fit;...
