摘要：We study the behavior of imitation and innovation in a dynamic general equilibrium model that captures the salient features of an information age. We study a world where innovations can be made but at a cost that reflects the type of goods. After innovation takes place, imitation is possible but again at some cost which reflects the nature of the good. We show that the behavior of innovation and imitation are very different for high information content goods and low information content goods a...

摘要：Does the common currency promote goods market integration within the EMU? We argue that such an effect is likely, but that the mechanism typically proposed-lower costs of arbitrage because of increased price transparency-is likely to be of minor importance. Instead we sketch a duopoly model which stresses that lower possibility of future real exchange rate variability lowers the option value of being able to price discriminate. The euro would promote market integration because it is less valua...

摘要：The IPOs of the Electricity/Internal Combustion revolution created more lasting value than the IPOs of the IT revolution. Stock-market data point to two explanations for this. First, computer prices have been falling much faster than did those of electricity and internal combustion in the 1890-1930 period, and so the value of each generation of computer-intensive entrants is reduced by later entrants. And, second, the pre-1973 vintages reacted to the microcomputer relatively quickly, perhaps b...

摘要：The role of field experiments in evaluating the effect of compensation policies on worker productivity is considered. Particular attention is paid to the ability of a field experiment to identify the effect of a permanent change in firm policy. While field experiments solve endogeneity problems through randomization, they do so within a specific, and at times artificial, environment that may not be replicated by a permanent policy change. As such, rather than providing a basis for the unrestri...

摘要：The paper analyses the interaction between economic incentives and work norms in the context of social insurance. If the work norm is endogenous in the sense that it is weaker when the population share of beneficiaries is higher, then voters will choose less generous benefits than otherwise. We also discuss welfare-state dynamics when there is a time lag in the adjustment of the norm in response to changes in this population share, and show how a temporary shift in the unemployment rate may ca...

摘要：This paper argues that the internal organization of the firm and the growth process interact strongly to determine simultaneously the power of incentives within the firm and the growth rate. We show how agents within the firm can invest either by using their own human capital or by relying on some form of reputational capital to secure implicit relationships within the firm and we discuss how these investments affect the growth rate of the economy.

摘要：Individual microcredit loans are not necessarily simple fixed debt obligations, but rather may have contingencies and procedures suggested by the theory of mechanism design. Further, group or joint-liability lending may not be the single miracle cure practitioners claim nor operate the way the logic of a single theory might suggest. There are multiple theories, these theories can be distinguished in data on repayment rates, and the best-fit theory may vary with the environment. Finally, the de...

摘要：We measure the past production of research articles by current members of European economics institutions. All EconLit journals are used, weighted to reflect differences in quality. Both a long (1971-2000) and a short (1996-2000) time period are considered. We also provide production indices that take into account the authors' career length. The total output of each research center is measured as well as its production per member. The focus is on 600 centers from eighteen European countries (E...

摘要：We conducted a worldwide ranking of academic institutions that produce research in a list of thirty top research journals in economics. We also computed journal rankings for the same period and hence we do not rely on weights that were computed for research carried out in earlier periods. The United States is clearly the dominant force in the top-fifty group, but European academic institutions are well represented in the group of the top 200 universities worldwide as are universities from Asia...

摘要：Many if not most markets with network externalities are two-sided. To succeed, platforms in industries such as software, portals and media, payment systems and the Internet, must get both sides of the market on board. Accordingly, platforms devote much attention to their business model, that is, to how they court each side while making money overall. This paper builds a model of platform competition with two-sided markets. It unveils the determinants of price allocation and end-user surplus fo...
