This study examines the effect of downstream firms’ (i.e., customers’) risk factor disclosures contained in annual reports on the investment efficiency of upstream firms (i.e., suppliers). We find that more informative disclosures of customers’ risk factors are associated with less under‐ or overinvestment by suppliers. In addition, this inverse association is stronger when the suppliers are at a bargaining disadvantage, when they operate in the durable goods industries, and when they are more concerned about the volatility of future demand. Overall, our results suggest that risk factor disclosures provided by firms in their annual reports contain useful information that could potentially help their suppliers achieve better investment efficiency.

ABSTRACTThis paper analyzes the extent to which technology progress and youth employment are related. In doing so, we divide workers into two groups – young workers and old (prime-aged) workers - and then estimate the elasticity of substitution between (physical) capital and workers à la Jaimovich et al. (2013. “The Demand for Youth: Explaining Age Differences in the Volatility of Hours.” American Economic Review 103 (7): 3022–3044) by using the Korean labour market data between 2000 and 2014. Our findings indicate that the elasticity of substitution is greater (or at least not smaller) for young workers than for old workers. 相似文献

This paper investigates the role of stochastic volatility and return jumps in reproducing the volatility dynamics and the
shape characteristics of the Korean Composite Stock Price Index (KOSPI) 200 returns distribution. Using efficient method of
moments and reprojection analysis, we find that stochastic volatility models, both with and without return jumps, capture
return dynamics surprisingly well. The stochastic volatility model without return jumps, however, cannot fully reproduce the
conditional kurtosis implied by the data. Return jumps successfully complement this gap. We also find that return jumps are
essential in capturing the volatility smirk effects observed in short-term options.

This paper reviews the evidence on the relationship between work and health. It concludes that, overall, the beneficial effects of work outweigh the risks of work, and are greater than the harmful effects of long-term worklessness. That contrasts with increasing trends of sickness absence, long-term incapacity and ill-health retirement attributed to common health problems. It suggests that there needs to be a fundamental shift in how we think about common health problems and work--in health care, the workplace and society. 相似文献

We analyze voting behavior in a large electorate in which voters have adversarial state-contingent preferences with incomplete information about the state of the world. We show that one type of voter can suffer from the swing voter's curse à la Feddersen and Pesendorfer [The swing voter's curse, Amer. Econ. Rev. 86 (1996) 408-424], and go on to characterize the symmetric Nash equilibria of this model under different parameter values. We prove that unlike settings with nonadversarial preferences, there are equilibria in which in one state of the world, a minority-preferred candidate almost surely wins the election and thus the election may fail to correctly aggregate information. Indeed, we show that the fraction of the electorate dissatisfied with the result can be as large as . 相似文献

This paper utilizes the instrumental variable threshold regressions approach to reassess the trade–development link. It finds evidence that trade openness contributes to uneven development. Greater trade openness tends to have beneficial effects on real development of high‐income countries. For low‐income ones, however, trade openness appears to influence real income in a significant and negative way. The data also reveal that greater trade openness has a positive effect on capital accumulation, productivity growth, and financial development in high‐income countries, but a negative impact in low‐income ones. 相似文献

This paper provides a theory and evidence that the risk premium puzzle is viewed as a phenomenon pertaining to the unstable
foreign exchange market. In an unstable market, revision error uncompensated by an initial risk premium accrues due to consumer
expectation revision about the ex ante uncertainty of the exchange rate. The risk premium widely deviates from its initial level, depending on the frequency of
the consumer expectation revision and the degree of risk aversion. Subsequent evidence shows the existence of the revision
errors for the risk premium during the Asian currency crisis and the recent financial crisis periods. 相似文献

Stochastic convergence of the catch-up rate and multiple structural breaks in Asian countries 总被引:1,自引:0,他引:1

Allowing for multiple structural breaks and cross-section dependence, we re-investigate the hypothesis that the catch-up rates stochastically converge for 13 Asian countries from 1960 to 2007. Non-rejection of stationarity provides evidence for stochastic convergence, implying that following shocks to the catch-up rate, it will eventually revert to its long-run level. 相似文献
