We model the widespread failure of contracts to share risk using available indices. A borrower and lender can share risk by conditioning repayments on an index. The lender has private information about the ability of this index to measure the true state that the borrower would like to hedge. The lender is risk-averse and thus requires a premium to insure the borrower. The borrower, however, might be paying something for nothing if the index is a poor measure of the true state. We provide sufficient conditions for this effect to cause the borrower to choose a nonindexed contract instead.  相似文献

According to a recent conjecture in the literature, earnings have become a poorer proxy for cash flow from operations over time. We find that since 1988, when cash flow statements started to be consistently reported in Compustat, the cash effectiveness of earnings has actually increased for a large sample of US manufacturing firms. This occurs despite the introduction of fair value accounting and increasing accounting accruals during the last three decades. Also contrary to the conjecture, using more comprehensive measures of cash flow does not restore the investment-cash flow sensitivity, which continues to be around 0.05 in more recent periods.  相似文献

Using data on job approval ratings of governors, U.S. senators, and the president, we find that firms located in states with high approval ratings outperform firms located in states with low approval ratings by .64% per month. Furthermore, this relationship is stronger when investors are actively involved in politics, when local politicians are closer to the center of political power, for small firms that have a larger proportion of local investors, and for financially strong areas where investors are ready to execute investments in local stocks. Overall, our study shows that investors’ political sentiment is important in determining stock returns.  相似文献

In this paper, we investigate how de facto financial globalisation has influenced the labour share in developing countries. Our main argument is the need to distinguish between different types of capital in this context as they differ in their effect on the host countries' production process and vary concerning their bargaining power vis-à-vis labour. Our econometric analysis of the impact of foreign direct versus portfolio investment in a sample of about 40 developing and transition countries after 1992 supports this claim. Using different panel data techniques to address potential endogeneity problems, we find that foreign direct investment has a positive effect on the labour share in developing countries, while the impact of portfolio investment is significantly smaller and potentially negative. Our results also highlight that de facto foreign investment cannot explain the decline of the labour share in developing countries over the investigated period.  相似文献

Consumers are increasingly bombarded with merchandise and offers, making clear the need for visually distinctive and sensorially engaging product packaging design. The current research demonstrates that the use of handwritten fonts on product packaging elicits an approach tendency and enhances haptic engagement, which influences product evaluation and choice likelihood. A pilot study quantifies the use of handwritten fonts in four grocery product categories to establish that the study of handwritten fonts as a packaging design element is a worthy one with managerial significance. Four experiments are then presented. Studies 1 and 2 use real products to show that a product label with a handwritten (vs. typewritten) font elicits haptic engagement and, enhanced product evaluations (Study 2). Study 3 identifies a boundary condition such that the focal effect is observed only for benign (safe and enjoyable) product categories, but not for risky (unsafe and dangerous) ones. Study 4 relies on a simulated store setup with actual products to illustrate the differential preference for products with a handwritten (vs. typewritten) font when choosing between brands in a benign (vs. risky) product category.  相似文献
