Technological Progress and Youth Employment in South Korea

ABSTRACT

This 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.     

The role of stochastic volatility and return jumps: reproducing volatility and higher moments in the KOSPI 200 returns dynamics

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.

Work and common health problems

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.     

The swing voter's curse with adversarial preferences

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 .

Nonlinearity between Trade Openness and Economic Development

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.     

Market Instability and Revision Error in Risk Premium

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.     

Stochastic convergence of the catch-up rate and multiple structural breaks in Asian countries

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.     

Negative externalities on property values resulting from water impairment: The case of the Pigeon River Watershed

The objective of this research was to determine whether willingness to bear the negative externality from water quality impairment differs between those who do and those who do not receive economic benefit from the impairment source. Differences were tested using a hedonic analysis of ambient water quality in two discrete housing markets in the Pigeon River Watershed, which have been polluted by the operation of a paper mill. The results suggest that North Carolina residents residing in subwatersheds with impaired portions of the Pigeon River, who experience economic benefit from the paper mill in addition to its harmful effects on water quality, do perceive the pollution as a negative externality. In contrast, the effects of both the degraded river and its contributing streams on property values are perceived as negative externalities by watershed residents in Tennessee who experience only harmful effects from the pollution. Differences in willingness to bear the water-impairment externality were not indicated by variables representing view of and proximity to impaired water bodies. The results suggest that the perception of water quality to which property owners implicitly apply value should be considered when establishing water-quality regulations.
