We document several empirical regularities regarding the evolution of urban structure in the largest U.S. metropolitan areas over the period 1980–90. These regularities relate to changes in resident population, employment, occupations, as well as the number and size of establishments in different sections of the metropolitan area. We then propose a theory of urban structure that emphasizes the location and internal structure decisions of firms. In particular, firms can decide to locate their headquarters and operation plants in different regions of the city. Given that cities experienced positive population growth throughout the 1980s, we show that firm fragmentation produces the diverse set of facts documented in the article. 相似文献

We present a model of economic growth driven by horizontal innovation in which, unlike the existing literature, the final output sector employs a non-specified, non-CES, additive production function. Our motivation in conducting such analysis is based on the recognition that the use of a CES aggregate production function in the final output sector leads to the unrealistic conclusion that the gross markup of price over marginal costs set in the monopolistically-competitive intermediate sector is constant. We derive necessary and sufficient conditions for an equilibrium with perfect competition in the final output market to exist even in the presence of a non-CES technology. These conditions generalize the usual properties of the CES case. We also analyze the long-run relation between economic growth and variable markups. 相似文献

This paper contributes to the organisational study of the creativity applied to business innovation through the analysis of three propositions: (1) there are substantial differences between Creative Entrepreneurial Initiatives (CEIs) and non-CEIs, with regard to human capital factors, structural capital factors, intellectual property, and creative value chain; (2) there are institutional, financial, and educational barriers that limit the creation of CEIs in South Europe (Portugal, France, and Spain); and (3) the adaptation of organisational measures of stimulus to the specificity of CEIs through a flow diagram can reduce the limiting effect of the barriers detected by CEIs. From this approach, researchers and policy-makers can obtain a better understanding of the specificities of the CIEs from a sectoral, strategic, and organisational focus. 相似文献

In a context of infinitely-lived families à la Sidrauski, where consumers are lump-sum compensated for the inflation tax, and there is no capital mobility, it is shown that a devaluation improves while an increase in the rate of devaluation deteriorates the balance of payments. 相似文献

This paper examines pricing policies for OPEC under the assumption that the cartel is composed of a block of spender countries with large cash needs and a block of saver countries with little immediate need for cash and a lower rate of discount. The decision problem for the two-part cartel is embodied in a game-theoretic framework and the optimal bargaining solution is computed using results from the theory of cooperative games developed by Nash. The set of feasible bargaining points—and the corresponding Nash solution—is computed under two assumptions on the behavior of output shares: that they are subject to choice and that they are fixed at historical values. Our results suggest that for fixed output shares, there is little room for bargaining, and the price path approximates the optimal monopoly price path. If the shares are subject to control, optimal paths depend significantly on the relative bargaining power of each block. 相似文献

High interest rates are considered an effective tool for stoppinghigh inflation. The case for a policy of high interest ratesis developed in terms of a conventional IS-LM model. However,among other things, the model ignores some central aspects ofmodern credit markets. In particular high interest rates maygive rise to nonperforming bank loans, thus seriously jeopardizingthe effectiveness of the policy. Examples are developed in whichit would be optimal to aim for equilibriums of low, rather thanhigh, interest rates. One of these examples hinges on the existenceof nonindexed domestic debt. 相似文献

This article carries out an empirical examination of the origin of the differences between immigrant and native-born wage
structures in the Spanish labour market. Special attention is given in the analysis to the role played by occupational and
workplace segregation of immigrants. Legal immigrants from developing countries exhibit lower mean wages and a more compressed
wage structure than native-born workers. By contrast, immigrants from developed countries display higher mean wages and a
more dispersed wage structure. The main empirical finding is that the disparities in the wage distributions for the native-born
and both groups of immigrants are largely explained by their different observed characteristics, with a particularly important
influence in this context of workplace and, specially, occupational segregation.

This paper analyzes optimal media planning strategies in a pricing‐advertising competition model where firms can use mass and specialized advertising. We find that although targeted advertising avoids the wasting of ads, firms might find it optimal to mix specialized advertising with the mass media. We also show that the characteristics of the specialized media available crucially affect the outcome of price competition between firms, which can range from a full fragmentation of the market into local monopolies to lower average prices (compared to the case where firms had only mass advertising available). Regarding welfare, we prove that although the use of specialized advertising can lower consumer surplus and drive a fragment of consumers out of the market, this advertising technology is welfare‐improving, and can be Pareto superior. 相似文献

We analyze the contribution of credit spread, house and stock price shocks to the US economy based on a time‐varying parameter vector autoregressive model. We find that the contribution of financial shocks to gross domestic product growth fluctuates from about 20% in normal times to more than 50% during the Great Recession. The Great Recession and the subsequent weak recovery can largely be traced back to negative housing shocks. Housing shocks have become more important for the real economy since the early 2000s, and negative housing shocks are more important than positive ones. Unexpected increases in credit spreads have not been deflationary recently. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

AbstractThis article investigates how contract employment practices adopted by universities—fixed-term contracts and permanent contracts—impact research productivity measured in terms of publications in scholarly journals. The empirical application considers the Spanish public higher education system for the period 2002–2008. We report an inverse U-shaped relationship between the rate fixed-term contracts and the research productivity of Spanish universities. That is, contract policies based on fixed-term contracts are conducive to research productivity; however, beyond a critical threshold value increases in the proportion of fixed-term contracts are associated with declining research productivity. These findings reveal that contract employment policies shape research productivity, and that flexible and balanced contract practices are critical for enhancing universities’ research productivity. The results suggest that the excessive use of fixed-term contracts might create an unstable working environment that limits the universities’ capacity to capitalize on their knowledge workers. Policy implications and future research avenues are discussed. 相似文献
