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

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

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

This paper presents two views of the European sovereign debt crisis. The first is that countries in the South of the Eurozone were fiscally irresponsible and failed to implement pro-competitive supply side policies. The second view holds that the crisis reflects a deep divide between the external surpluses of the North and external deficits of the South. Basic stylized facts cast doubt on the explanation based on the first thesis alone. A relatively simple model shows how poor fundamentals can create a debt problem independently of fiscal responsibility. The empirical analysis of the determinants of government bond yield spreads relative to Germany suggests that both views in fact provide useful insights into the roots of the current sovereign crisis. However, differences in growth and competitiveness and capital flows between North and South have assumed a much more dominant role since the onset of the global crisis.  相似文献

Hyman Minsky's Financial Instability Hypothesis (FIH) is applied to various North American Industrial Classification System (NAICS) industry groups, and it is found that some sectors develop much more closely in accordance with the FIH than others. Minsky categorized firms based on the relationship between cash flow and debt service requirements: hedge finance units, whose operating revenues are adequate to service current interest and principal on their debt; speculative finance units, which can meet interest payments but cannot pay down principal; and Ponzi finance units, which cannot meet current interest payments. The FIH is related to, as well as supportive of, Austrian Business Cycle (ABC) theory, because interest rates are negatively correlated with the proportion and market value of speculative firms in several sectors.  相似文献

This article examines the role of multinational companies (MNCs) in the growth of the U.S. trade deficit. Estimates of MNC-related trade are developed for 1977, 1982, and 1987. The data show that MNCs are associated with a significant share of U.S. trade and that the trading activities of multinational companies can be linked to significant trends in the U.S. trade balance.  相似文献

This article documents the popularity of five types of trail-based recreation relative to other forms of recreation that tourists frequently participate in on their trips; identifies these trail users’ cross-participation in other outdoor recreation activities; and profiles the travel behaviour, media habits, trip planning behaviour, and demographic and socioeconomic characteristics of day hikers and snowmobilers as two particularly large trail user segments. Findings are based on data from a household telephone survey conducted in Michigan, surrounding states, and Ontario, Canada. Hiking/backpacking was found to be the most popular natural resource-based recreation activity that respondents participated in on pleasure trips taken during the past 12 months; other forms of trail-based recreation were significantly less popular; mountain bikers participated in nature-oriented recreation activities in Michigan at levels that were similar to those of hikers/backpackers; and snowmobiling appeared to be the focus of most pleasure trips on which this activity occurred, in contrast to day hiking, which appeared to be more of an ancillary pursuit.  相似文献

A widely held view is that immigrants contribute to public debt through their over representation in the unemployment benefit programme. An empirical investigation, based on the 1990 Income Distribution Survey, finds support for this view. In contrast to the US and Canadian studies, this paper observes that the probability of receiving unemployment benefits is higher for immigrants than the native-born population and immigrants, who participate in the unemployment benefit programme, also receive a greater amount of unemployment benefits.  相似文献
