We study how two fiat monies, one safe and one risky, compete in a decentralized trading environment. The currencies' equilibrium values, their transaction velocities and agents' spending patterns are endogenously determined. We derive conditions under which agents holding diversified currency portfolios spend the safe currency first and hold the risky one for later purchases. We also examine when the reverse spending pattern is optimal. Traders generally favor dealing in the safe currency, unless trade frictions and the currency risk is low. As risk increases or trading becomes more difficult, the transaction velocity and value of the safe money increases. 相似文献

The paper investigates the changes in job creation and destruction flows at a very disaggregated level of analysis. We analyse whether job flows at lower levels of spatial aggregation display regularities that are in line with national ones in a bid to disentangle the role of labour market institutions. Using a unique database of the population of firms in Trentino (a north‐eastern province of Italy) from 1991 to 2001, we find that: (1) job flows show a ‘fractal’ tendency, i.e. many regularities appear to be scale invariant (magnitude of flow and persistence) and that job flow magnitude is in line with the average values for Italy; (2) there are some qualifications to their ‘fractality’: the contribution of entrant firms to the job creation process is lower than the corresponding contribution at national level, as is the share of job destruction accounted for by exiting firms; and (3) firm size and age influence job flows. 相似文献

This paper presents panel evidence on the productivity effects of middle managers’ off‐the‐job formal training in Italy. It is based on a rich and reliable panel dataset covering all sectors of the Italian economy over the period 2006–2011. We employ panel data techniques and self‐selection models to show that off‐the‐job formal training for middle management has a significant nonlinear exogenous effect on total factor productivity. Moreover, results indicate that middle managers’ off‐the‐job formal training is more effective in larger firms and that different training methods have heterogeneous effects on productivity. 相似文献

We relax restrictions on the storage technology in a prototypical monetary search model to study price dispersion. In this case, buyers and sellers enter matches with potentially different willingness to trade. Across the distribution of possible bilateral matches, prices generally will differ even though agents have identical preferences and technologies. We provide existence conditions for a particularly simple equilibrium pattern of exchange. We prove that in the limiting case where search frictions are eliminated, equilibrium prices are uniform. We also show that a higher initial money stock can raise the average price level and increase price dispersion. 相似文献

This research investigates the effects of visual cues depicted on food packaging on consumers’ estimates of the contained amount and consumers’ self-control intentions. Results from two experiments show that the number of product units shown on the package drives perceptions and behavioral intentions in food categories where product size tends to be quite standardized, supporting the “see more, expect more” effect reported by previous literature, but adding a “see virtue, expect more” effect triggered by product type. Instead, when product size tends to vary across manufacturers, picture size has a greater effect on consumers’ content estimations and self-control intention than the number of product units depicted, suggesting the existence of a “see small, expect more” effect according to which consumers estimate larger content when the package portrays smaller product units. Results stimulate awareness of the effects that can be conveyed by images on packaging, on content estimates and consumer self-control. 相似文献

We derive computationally simple expressions for score tests of misspecification in parametric dynamic factor models using frequency domain techniques. We interpret those diagnostics as time domain moment tests which assess whether certain autocovariances of the smoothed latent variables match their theoretical values under the null of correct model specification. We also reinterpret reduced‐form residual tests as checking specific restrictions on structural parameters. Our Gaussian tests are robust to nonnormal, independent innovations. Monte Carlo exercises confirm the finite‐sample reliability and power of our proposals. Finally, we illustrate their empirical usefulness in an application that constructs a US coincident indicator. 相似文献

This article analyses the relationship between a university’s score in international university rankings, its expenditure per student and other factors such as university mission, size and productive inefficiency. We develop an economic model of rankings and universities and estimate this model with data on universities classified in the top 200 by the Times Higher Education Supplement ranking of 2007. We find that the elasticity of a university’s ranking score for the expenditure per student is between 4% and 9%, and that there are no clear signs of inefficiency in production among the top 200 universities. University mission and size are also significant predictors of ranking score. These results are especially interesting given the relevance attributed to rankings by government officials, university directors and students. 相似文献
