Models driven by Lévy processes are attractive because of their greater flexibility compared to classical diffusion models. First we derive the dynamics of the LIBOR rate process in a semimartingale as well as a Lévy Heath-Jarrow-Morton setting. Then we introduce a Lévy LIBOR market model. In order to guarantee positive rates, the LIBOR rate process is constructed as an ordinary exponential. Via backward induction we get that the rates are martingales under the corresponding forward measures. An explicit formula to price caps and floors which uses bilateral Laplace transforms is derived. 相似文献

Although reserve requirements (RR) have been used in emerging markets to smooth credit cycles, the transmission mechanism remains blurry. Using bank‐level data, we unveil the interaction of RR with bank lending. We identify a new channel that works through a decline in banks’ liquid assets and loan supply due to an increase in RR. “Quantitative tightening” through RR raises the short‐term funding needs of the banking system, which is met by collateralized central bank lending, thus depleting banks’ unencumbered liquid assets. Our results suggest that such a shift in bank liquidity is associated with a significant change in lending. 相似文献

Researchers and companies are paying increasing attention to corporate social responsibility (CSR) programs and the reaction to them by consumers. Despite such corporate efforts and an expanding literature exploring consumers’ response to CSR, it remains unclear how consumers perceive CSR and which “Gestalt” consumers have in mind when considering CSR. Academics and managers lack a tool for measuring consumers’ perceptions of CSR (CPCSR). This research explores CPCSR and develops a measurement model. Based on qualitative data from interviews with managers and consumers, the authors develop a conceptualization of CPCSR. Subsequently, model testing and validating occurs on three large quantitative data sets. The conceptualization and the measurement scale can assist companies to assess CPCSR relative to their performance. They also enable managers in identifying shortcomings in CSR engagement and/or communication. Finally, the paper discusses implications for marketing practice and future research. 相似文献

Understanding the implications of increased foreign bank presence is especially compelling in periods of financial crisis. In this paper, we explore this issue by examining the relationship between the involvement of foreign banks in the banking systems and the volatility of key macroeconomic variables in normal and crisis periods. Using a sample of 20 Emerging European countries from 1998 to 2013, we find that an increase in the assets of foreign banks in the banking system reduces output and consumption growth volatility in general but does not significantly affect the volatility of investments. However, these banks were found to play a significant role in increasing output, consumption and investment volatility in 2009. Our findings suggest that foreign banks’ harmful impact during the global crisis was only temporary and that they seem to help Emerging European countries stabilize macroeconomic volatility in normal times and after the global crisis. 相似文献

Are hedging transactions that diversify a manager’s compensation risk detrimental to incentives, or can they improve contracting efficiency? If hedging provides efficiency benefits, should the manager or the firm undertake it? In our model, both the firm and the manager can trade financial portfolios to diversify the manager’s compensation risk. Prior to the portfolio selection, the parties need to acquire information on how different financial portfolios fit their diversification purposes. We illustrate that financial portfolios correlated with firm‐specific risk improve contracting efficiency. For equal information costs, it is optimal for the firm to undertake the hedging on the manager’s behalf. 相似文献

Sustainability practices are critical for family firms, as they relate directly to the continuity of the business and relationships with important stakeholders, such as members of the local community. Nevertheless, not all family firms wish to adopt sustainability practices. To examine this, we draw upon the socioemotional wealth perspective in order to develop a theoretical model of the direct negative effects of family ownership on the adoption of sustainability practices. We also suggest moderating effects of long-term orientation (LTO) on this link. Our model is tested on a sample of 195 family firms in the tourism and hospitality sector. The results support our hypothesis that family ownership negatively influences the adoption of sustainability practices. Additionally, LTO moderates the relationship between family ownership and the adoption of sustainability practices, such that family owners with a high LTO are more likely to adopt this particular practice compared to those with a low LTO. 相似文献

This study uses GARCH-EVT-copula and ARMA-GARCH-EVT-copula models to perform out-of-sample forecasts and simulate one-day-ahead returns for ten stock indexes. We construct optimal portfolios based on the global minimum variance (GMV), minimum conditional value-at-risk (Min-CVaR) and certainty equivalence tangency (CET) criteria, and model the dependence structure between stock market returns by employing elliptical (Student- and Gaussian) and Archimedean (Clayton, Frank and Gumbel) copulas. We analyze the performances of 288 risk modeling portfolio strategies using out-of-sample back-testing. Our main finding is that the CET portfolio, based on ARMA-GARCH-EVT-copula forecasts, outperforms the benchmark portfolio based on historical returns. The regression analyses show that GARCH-EVT forecasting models, which use Gaussian or Student- copulas, are best at reducing the portfolio risk. 相似文献

The paper investigates the long-run relationships between budget deficits, inflation and monetary growth in Turkey considering two alternative trivariate systems corresponding to the narrowest and the broadest monetary aggregates. While the joint endogeneity of money and inflation rejects the validity of the monetarist view, lack of a direct relationship between inflation and budget deficits makes the pure fiscal theory explanations illegitimate for the Turkish case. Consistent with the policy regime of financing domestic debt through the commercial banking system, budget deficits lead to a growth not of currency seigniorage but of broad money in Turkey. This mode of deficit financing, leading to the creation of near money and restricting the scope for an effective monetary policy, may not be sustainable, as the government securities/broad money ratio cannot grow without limit. 相似文献

U.S. stocks are more volatile than stocks of similar foreign firms. A firm's stock return volatility can be higher for reasons that contribute positively (good volatility) or negatively (bad volatility) to shareholder wealth and economic growth. We find that the volatility of U.S. firms is higher mostly because of good volatility. Specifically, stock volatility is higher in the United States because it increases with investor protection, stock market development, new patents, and firm‐level investment in R&D. Each of these factors is related to better growth opportunities for firms and better ability to take advantage of these opportunities. 相似文献
