This article develops a mechanism to measure the impact of local content requirements as quantitative restrictions. We compare effects of the novel quantitative approach to the effects of a tariff equivalent, which is more traditionally used to analyse these types of policies. Local content requirements increase output and value added in the affected sector, but at the expense of other sectors, leading to declines in GDP and trade across the economy. Comparing the two modelling approaches, the differences in outcomes are shown to be significant.  相似文献

Turnovsky observes that “the rational expectations hypothesis has had a profound impact on macroeconomic theory and policy during the past decade.” Tracing briefly the evolution of the ideas involved, he concludes that “… a consensus view is emerging that in fact under quite plausible conditions the policy neutrality proposition does not hold; therefore, there is still scope for policy rules to play an important role in stabilizing output.”

The mathematics used in the article is expository rather than analytical, requiring of the reader only somewhat more than the usual amount of persistence, faith in the author's interpretation of the literature, and a willingness to accept the integrity of economic models as representative of the real world. This is “required” reading for those teaching macroeconomics.  相似文献

Does the presence of corporate headquarters in a city affect the incomes of local charities? To address this question we combine data on the head office locations of publicly traded U.S. firms with information on the receipts of local charitable organizations. Cities like Houston, San Jose, and San Francisco gained significant numbers of corporate headquarters over the past two decades, while cities like Chicago and Los Angeles lost. Our analysis suggests that attracting or retaining the headquarters of a publicly traded firm yields approximately $3–10 million per year in contributions to local non-profits. Likewise, each $1000 increase in the market value of the firms headquartered in a city yields $0.60–1.60 to local non-profits. Most of the increase in charitable contributions is attributable to an effect on the number of highly-compensated individuals in a city, rather than through direct donations by the corporations themselves. The increased private sector donations from the presence of corporate headquarters do not seem to crowd out government grants to local charities.  相似文献

Product selection matters for a firm's productivity and long-run growth. Recent theoretical and empirical studies indicate that an important margin of adjustment to policy reforms is the reallocation of output within firms through changes in product mix decisions. This paper examines the frequency, pervasiveness and determinants of product-switching and upgrading activities in firms located in China's state-owned forest areas during a period of gradual institutional and managerial reforms (2004–2008). We find that changes to the product mix are pervasive and characterized by adding or churning products rather than only shedding products. Moreover, changes in firms’ product mix have made a significant contribution to the aggregate output growth during our sample period. We also find that firms with different characteristics, human capital and market conditions differ in their propensity to diversify and upgrade product mix.  相似文献

This brief exploratory empirical note seeks to identify key determinants of geographic differentials in the percentage growth rate of state-level employment in the US, with the primary focus being on the percentage net growth rate in the number of small firms (i.e., those with fewer than 20 employees) in each state, where this variable serves as a de facto reflection of ‘entrepreneurship’. In the interest of identifying other key factors that influence state-level employment growth rates, the effective income tax rate in each state, quality of life elements and labour market considerations are also included in the analysis. The study period runs from the year 2000 to the year 2007, ending just prior to the ‘Great Recession’. The estimation results imply that the state-level employment growth rate in the US was an increasing function of the percentage net growth rate in the number of small firms in each state. Thus, it appears that the small firms growth rate may in fact be a significant source.  相似文献

The country-of-origin effect (COE) on employment practices in multinational enterprises (MNEs) has become an important area of international human resource management research. However, research on the mechanisms of the COE, a fundamental and critical aspect of the country-of-origin phenomenon, is scant. This study seeks to empirically explore the mechanisms through which country-of-origin influences Chinese MNEs’ approach to host-country employer associations. Analysis of qualitative data from 13 Chinese MNEs revealed that country of origin affected the approach of Chinese MNEs to host-country employer associations in the form of transfer of managerial norms. It also revealed that it was the mindset of those home-country nationals who were key decision-makers at subsidiaries that enabled the COE in Chinese MNEs. This paper highlights the importance for future studies of international strategic human resources management to pay attention to micro-foundations of cross-border practice transfer and to incorporate analyses of managerial cognition in the investigation of MNEs’ management practices.  相似文献

In numerous psychology studies, subjects are asked to perform some task a number of times, T. The effect of the choice of T on the associated inference, however, is usually not assessed. We investigate the appropriate choice of T empirically by using data collected in a study on the relationship between psychopathy and risk-taking in 90 inner city drug users enrolled in a residential treatment program. We show that, when studying this relationship, the latency variable usually discarded from the analysis behaves exponentially allowing a natural division of the study period 1, . . . , T into two distinct subperiods. These subperiods yield significantly different results—in the early period only (which we call “reactive”), subjects with high psychopathy scores exhibit lower sensitivity to reward and punishment in our risk taking experiment. The later period (which we call “stable”) shows no relationship between sensitivity to reward and punishment and psychopathic tendencies.  相似文献

We revisit the interest rate pass-through effect using weekly retail banking data from May 2006 to March 2010. Our choice of data avoids caveats of previous studies concerning excessive data aggregation and the estimation of how fast changes in benchmark interest rates impact those charged on short-term loans in Brazil. Our analysis focuses on four large retail banks – two of them privately owned and run, two of them government-controlled – before and after September 2008. They account for 60% of the total credit supplied by retail banks. Results indicate that government control over two of the largest banks, supposedly an asset for crisis management, may have had higher welfare costs than assumed. We find no evidence of asymmetry in adjustments of retail rates charged by private and government-controlled banks.  相似文献
