ABSTRACT

This paper first measures the levels and growths of regional TFP in China using a panel dataset of China’s 30 provinces from 1978–2014. It then estimates the effects of R&D on regional TFP and its growth further explores the impact of TFP on China’s energy intensity. We find no evidence that R&D has innovation and spillover effects on TFP and its growth in China’s provinces. Nevertheless, R&D can promote growth in regional TFP by helping to absorb new technologies embodied in FDI and foreign trade. The results indicate that TFP plays a significant role in the decline of China’s energy intensity.  相似文献

Cross hedging price risk in an incomplete financial market creates basis risk. We propose a new way of modeling basis risk where price risk and basis risk are combined in a multiplicative way. Under this specification, positive prudence is a necessary and sufficient condition for underhedging in an unbiased market. Using the example of cross hedging jet fuel price risk with crude oil futures, we show that the new specification is superior in describing the price series and that optimal cross hedges differ significantly from those derived under the traditional additive cross hedging model.  相似文献

We develop a stochastic programming model to address in a unified manner a number of interrelated decisions in international portfolio management: optimal portfolio diversification and mitigation of market and currency risks. The goal is to control the portfolio’s total risk exposure and attain an effective balance between risk and expected return. By incorporating options and forward contracts in the portfolio optimization model we are able to numerically assess the performance of alternative tactics for mitigating exposure to the primary risks. We find that control of market risk with options has more significant impact on portfolio performance than currency hedging. We demonstrate through extensive empirical tests that incremental benefits, in terms of reducing risk and generating profits, are gained when both the market and currency risks are jointly controlled through appropriate means.  相似文献

This study explores how information costs, proxied by characteristics of credit reporting systems, affect the foreign expansion of the top 100 multinational banks. We find that banks prefer to expand operations in countries where private credit bureaus exist or where the credit reporting system is of better quality. This preference is particularly strong for banks’ branch decisions. Furthermore, banks prefer subsidiary entry only in countries where private credit bureaus exist with better credit information quality. Overall, our results indicate that banks are attracted to countries where the credit reporting system helps reduce banks’ information costs.  相似文献

This paper assesses how much mortgage interest rates in Italy are priced on credit risk as proxied by the probability of household mortgage delinquency estimated using the EU-Silc database. Owing to data availability, we restrict the analysis of mortgage pricing to Italian households. Consistent with the more widespread use of credit scoring, estimates indicate that Italian lenders have increasingly priced mortgage interest rates on household credit risk. For mortgages granted between 2000 and 2007, we find that a 1% point increase in the probability of default is associated with a 21 basis point rise in mortgage interest rates, lower than the 38 basis point premium Edelberg (2006) estimated for the US at the end of the 1990s.  相似文献

This paper addresses the effects of bank competition on the risk-taking behaviors of banks in 10 Latin American countries between 2003 and 2008. We conduct our empirical approach in two steps. First, we estimate the Boone indicator, which is a measure of competition. We then regress this measure and other explanatory variables on the banking “stability inefficiency” derived simultaneously from the estimation of a stability stochastic frontier. Unlike previous findings, this paper concludes that competition affects risk-taking behavior in a non-linear way as both high and low competition levels enhance financial stability, while we find the opposite effect for average competition. In addition, bank size and capitalization are essential factors in explaining this relationship. On the one hand, the larger a bank is, the more it benefits from competition. On the other hand, a greater capital ratio is advantageous for banks that operate in collusive markets, while capitalization only enhances the stability of larger banks under high and average competition. These results are of extreme importance when considering bank regulations, especially in light of the recent turmoil in the global financial markets.  相似文献

This study assesses whether the sale method in residential real estate markets – auction versus private treaty – is a determinant of sale price. Utilising a larger and richer dataset than previous research, we test for a price effect in auction sales in Sydney and Christchurch. When self‐selection biases are corrected for, using two‐stage hedonic regression analysis and a matched sampling procedure, we find no significant difference between prices of properties sold at auction to those sold by private treaty. This conflicts with the conclusions of previous research in the Australian and New Zealand housing markets, which have documented a price premium associated with auction sales.  相似文献

There is growing policy interest in charitable giving in the UK. As part of its Big Society agenda, the current government is keen to encourage a higher level of donations, highlighting new technologies, new social norms and tax incentives as potential mechanisms for raising giving. In the 2012 Budget, however, the Chancellor also proposed limiting tax relief on donations to £50,000, sparking an intense discussion about the effectiveness and desirability of tax incentives for major donors. This paper brings together recent evidence relevant to the ongoing policy debates.  相似文献

Young people in the UK consume far above the maximum recommended levels of added sugar. It is likely that neither they nor their parents fully take account of the future health, social and economic costs of this high sugar consumption. This provides a rationale for policy intervention. The majority of young people's added sugar consumption occurs in the home, where purchases are typically made by parents. This means that understanding the purchase decisions of adults is important for policy design, even if the policies aim to reduce the consumption of young people. We discuss the merits of popular policies, including taxes, advertising restrictions and restrictions on the availability of specific foods, and we identify promising avenues for future research.  相似文献

Antitrust regulators play a critical role in protecting market competition. We examine whether the political process affects antitrust reviews of merger transactions. We find that acquirers and targets located in the political districts of powerful U.S. congressional members who serve on committees with antitrust regulatory oversight receive relatively favorable antitrust review outcomes. To establish causality, we use plausibly exogenous shocks to firm–politician links and a falsification test. Additional findings suggest congressional members’ incentives to influence antitrust reviews are affected by three channels: special interests, voter and constituent interests, and ideology. In aggregate, our findings suggest that the political process adversely interferes with the ability of antitrust regulators to provide independent recommendations about anticompetitive mergers.  相似文献
