Systematic differences in the timing of wage-setting decisions among industrialized countries provide an ideal framework to study the importance of wage rigidity for the transmission of monetary policy. Synchronization in wage-setting decisions is prevalent in Japan and the United States, yielding varying degrees of wage rigidity within the year; instead, in France, Germany, and the United Kingdom decisions are more uniformly spread over time. Exploiting within-year variation in the timing of wage-setting decisions in these economies, we find support for the long-held but scarcely tested view that wage rigidity plays a critical role in the transmission of monetary policy. 相似文献

This paper examines equilibrium trade policies when firms have better information than governments about the profitability of the industry. Contrary to the intuition that the policymakers' lack of information should reduce their incentives to engage in strategic trade intervention, the analysis suggests that information asymmetries may increase trade policy distortions in equilibrium and ultimately worsen the "prisoner's dilemma" between governments. 相似文献

The paper analyzes the relationship between stock prices and fundamentals for a large sample of US stocks in the last 10 years
using a random coefficient model. Heterogeneity and omitted variable bias are properly taken into account with model coefficients
being allowed to vary across time and industries. The random coefficient model allows to track waves of reliance on analysts’
forecasts and nonfundamental stock price components across time and clearly identifies the growth of the nonfundamental component
in the long 1991–2000 swing.

Using a model with constant relative risk-aversion preferences, endogenous labor supply and partial insurance against idiosyncratic wage risk, this paper provides an analytical characterization of three welfare effects: (a) the welfare effect of a rise in wage dispersion, (b) the welfare gain from completing markets, and (c) the welfare effect from eliminating risk. The analysis reveals an important trade-off for these welfare calculations. On the one hand, higher wage uncertainty increases the cost associated with missing insurance markets. On the other hand, greater wage dispersion presents opportunities to raise aggregate productivity by concentrating market work among more productive workers. Welfare effects can be expressed in terms of the underlying parameters defining preferences and wage risk or, alternatively, in terms of changes in observable second moments of the joint distribution over individual wages, consumption and hours. 相似文献

“To Own or Not to Own?” A Study on the Determinants and Consequences of Alternative Intellectual Property Rights Arrangements in Crowdsourcing for Innovation Contests 下载免费PDF全文

Firms are increasingly engaging in crowdsourcing for innovation to access new knowledge beyond their boundaries; however, scholars are no closer to understanding what guides seeker firms in deciding the level at which to acquire rights from solvers and the effect that this decision has on the performance of crowdsourcing contests. Integrating property rights theory and the problem‐solving perspective while leveraging exploratory interviews and observations, we build a theoretical framework to examine how specific attributes of the technical problem broadcast by firms affect the seekers’ choice between alternative intellectual property rights (IPR) arrangements that call for acquiring or licensing‐in IPR from external solvers (i.e., with high and low degrees of ownership, respectively). Each technical problem differs in the knowledge required to be solved as well as in the stage of development of the innovation process and seeker firms pay great attention to such characteristics when deciding about the IPR arrangement they choose for their contests. In addition, we analyze how this choice between acquiring and licensing‐in IPR, in turn, influences the performance of the contest. We empirically test our hypotheses analyzing a unique dataset of 729 challenges broadcast on the InnoCentive platform from 2010 to 2016. Our results indicate that challenges related to technical problems in later stages of the innovation process are positively related to the seekers’ preference toward IPR arrangements with a high level of ownership, while technical problems involving a higher number of knowledge domains are not. Moreover, we found that IPR arrangements with a high level of ownership negatively affect solvers’ participation and that IPR arrangement play a mediating role between the attributes of the technical problem and the solvers’ self‐selection process. Our paper contributes to the open innovation and crowdsourcing literature and provides practical implications for both managers and contest organizers. 相似文献

This paper studies tariff‐tax reforms in a two‐region global New Keynesian model composed of a developing and an advanced region. In our baseline calibration, a revenue‐neutral reform that lowers tariffs in developing countries can reduce domestic welfare. The reason is that the increase in developing countries welfare due to higher output is dominated by the welfare losses stemming from the deterioration of the terms of trade. On the other hand, the reform increases output and welfare in the advanced countries and in the world as a whole. The effects that we highlight have not been studied in previous contributions to the literature, which looks at tariff‐tax reforms using a small open economy framework. Nominal rigidities have important implications for adjustment dynamics in our model. In the case of a ‘point‐for‐point’ reform, for example, price stickiness implies that the international dynamics of output is reversed compared to a revenue‐neutral reform. 相似文献

How sustainable are the current social security systems in the developed economies, given the projected demographic trends? The most recent literature has answered this question through dynamic general-equilibrium models in a closed-economy framework. This paper provides a new quantitative benchmark of analysis for this question represented by a two-region model (South and North) of the world economy where capital flows across regions. The timing and the extent of the demographic transition—and the associated economic forces shaping capital accumulation and equilibrium factor prices—are very different in the two regions. Thus, the projected paths of interest rate and wage rate in the North diverge substantially between closed and open economy. We perform a wide range of policy experiments under both scenarios. Our main conclusion is that if one is interested in quantifying the path of the fiscal variables (e.g., the value of the payroll tax) needed to keep the social security system viable or to finance a transition towards a fully funded system, then these two benchmarks yield similar results. However, if the focus is on quantifying the path of factor prices, aggregate variables and, ultimately, welfare, then the two approaches can diverge significantly. 相似文献

The article examines the determinants of the growth aspiration of Venezuelan entrepreneurs. We use the GEM database and build an econometric model based on a set of exogenous variables grouped into three large categories: contextual or environmental factors, individual factors and business variables. Given the Venezuelan specific characteristics, we place a particular focus on understanding the differences between entrepreneurs belonging or not to the BoP. The primary findings of this work are the identification of the variables that explain growth aspiration, namely, belonging to the BoP, gender, education, motivation and years of study and some additional variables where individual factors interact with the contextual factor BoP. The second finding is that there are significant differences for the entrepreneurs belonging and not belonging to the BoP, with a threshold where the entrepreneurs of the BoP become averse to continuing to aspire to growth. Practical and policy implications are elaborated with the results. 相似文献

Abstract This study uses an innovative research tool to evaluate the hypothesis of a consumer–environment interaction. A new computer graphics methodology keeps track of the time spent and the number of purchases made during shopping, together with several other behavioural measures. A laboratory experiment uncovered an interaction effect in dwell time and number of purchases between the type of shopping trip (fill-in trip vs. major trip) and the consumers' layout preference. Shoppers taking major trips were more prone to shop in a free-form layout, whereas those taking fill-in trips tended to prefer a grid layout. The article discusses implications for research and practice, identifying areas for future research. 相似文献

In a setting with a wishful thinking agent and a realistic principal, the paper studies how incentive contracts should be designed to control for both moral hazard and self‐deception. The properties of the contract that reconcile the agent with reality depend on the weight the agent attaches to anticipatory utility. When this is small, principal and agent agree on full recollection. For intermediate values the principal bears an extra cost to make the agent recall bad news. For large weights, the principal gives up on inducing signal recollection. We also extend the analysis to the case in which the parameter of anticipatory utility is private information. 相似文献
