Rules of origin of free trade arrangements limit the use of inputs from outside the preferential trade zone. A government negotiating a future FTAcan manipulate these rules in order to achieve national welfare objectives. The correct definition of rules of origin may help to enhance demand for domestically produced goods, promote national technological development, and maximize labour income. This paper proves that a more stringent rule of origin implies an increase of demand for the domestic factor if the substitution effect prevails over the effects caused by the decrease of the scale of operation in the domestic plant, and the reallocation of output between domestic and foreign plants. We further show that policy decisions regarding rules of origin that intertemporally maximize welfare and foster domestic technological evolution should be made at the greatest level of disaggregation that is feasible.  相似文献

For a small tariff-imposing country, within the standard two-commodity two-factor model of international trade, this paper reconsiders the implications of an inflow of capital from abroad. When the host country continues to import the capital-intensive good while remaining incompletely specialized, the analysis shows that the capital inflow must reduce host-country welfare, assuming that the foreign capital receives the full (untaxed) value of its marginal product. Under other circumstances considered, however, the inflow may have different consequences for welfare.  相似文献

A monthly index of “bad” news about China as reported in the USA from January 1990 to December 2008 is developed in this paper. “Bad” is defined as news touching on the following issues: human rights, Tibet, child labor, democracy, and repression. Using this bad news index, this paper documents a peculiar finding: 3–4 months after a trade deficit shock to the US–China bilateral trade balance, the frequency of bad news published about China by US media outlets rises sharply, then dies off slowly. Statistical analysis reveals that the likelihood that this finding is just a coincidence is relatively small—about 1%. In addition, this paper finds a robust association between the annual number of Congressional hearings on China and the US–China bilateral trade deficit. These results suggest that “China bashing” may be endogenous to fluctuations in the US–China bilateral trade balance.  相似文献

This paper discusses the determinants of the Mexican peso devaluation of December 1994. An examination of basic economic data reveals the shortcomings of existing explanations based on either inconsistent macroeconomic policies or self-fulfilling prophecies. We argue in contrast that the devaluation was related to the exhaustion of the disinflationary programme launched in the late 1980s, and that the timing of policy change was critically influenced by a conflict between the inherited disinflationary stance and the economic goals of the administration taking office in December 1994. The analysis suggests that a prolonged period of real currency appreciation before the devaluation was made possible not only by the strong inflationary aversion of the authorities but by a series of positive shocks that reduced the appreciation's negative effects.  相似文献

Organizations are becoming more and more aware of how important it is to strengthen the competences of their project managers. This fact acquires greater relevance in the development and international cooperation sector because of the need to have qualified professionals who can take up the challenges and address the specific demands of an ever more demanding and constantly evolving sector. This article provides the results of research that more than 100 experts in project management and administration participated in to detect which competences are the most relevant in this context.  相似文献

Transnational terrorism in Western countries has raised questions about security measures that constrain civil liberties. This is the first paper that uses a terrorist attack, that in the London 7/7/2005, as an exogenous source of variation to study the dynamics of risk perception and the effect on the readiness to trade off civil liberties for enhanced security. In this framework we show that willingness to trade off security for liberties is dramatically affected by changes in individual risk assessments due to a terrorist attack. We document the extent of persistence of changed attitudes.  相似文献

Bounds on European Option Prices under Stochastic Volatility   总被引:5,自引:0,他引:5  
In this paper we consider the range of prices consistent with no arbitrage for European options in a general stochastic volatility model. We give conditions under which the infimum and the supremum of the possible option prices are equal to the intrinsic value of the option and to the current price of the stock, respectively, and show that these conditions are satisfied in most of the stochastic volatility models from the financial literature. We also discuss properties of Black–Scholes hedging strategies in stochastic volatility models where the volatility is bounded.  相似文献

This paper provides evidence that audit reports convey relevant evidence for inferring the existence of underlying, unrevealed, financial imbalances. Unlike previous works, which studied US listed-firms bankruptcy, our research deals with Spanish non-financial SMEs under financial stress. Our results indicate that the audit of distressed SMEs has several distinctive features: higher auditor rotation, more qualified reports, and non-compliance with deadlines to approve and file the annual financial statements. We use this evidence to build and test a parsimonious and reliable forecast model. Several implications for auditors’ independence, information quality, and failure forecast are discussed.  相似文献

Based on studies of idiosyncratic volatility developed in the recent literature, this study analyzes its relation with expected returns through the breakdown of idiosyncratic volatility in the Brazilian stock market and presents evidence of the importance of expected idiosyncratic volatility for asset pricing. We study the impact of the expected and unexpected components of idiosyncratic volatility on the returns of shares listed on the BOVESPA between 2004 and 2011. The results show a strong positive and significant relation between expected idiosyncratic volatility and returns. This evidence is highlighted when we use unexpected idiosyncratic volatility to control for unexpected returns. Additional robustness tests, controlling for size and momentum effects, also have positive and significant coefficients, corroborating previous findings.  相似文献
