Risk,uncertainty and monetary policy

The VIX, the stock market option-based implied volatility, strongly co-moves with measures of the monetary policy stance. When decomposing the VIX into two components, a proxy for risk aversion and expected stock market volatility (“uncertainty”), we find that a lax monetary policy decreases both risk aversion and uncertainty, with the former effect being stronger. The result holds in a structural vector autoregressive framework, controlling for business cycle movements and using a variety of identification schemes for the vector autoregression in general and monetary policy shocks in particular. The effect of monetary policy on risk aversion is also apparent in regressions using high frequency data.     

Internationalization of Italian Firms in Central and Eastern European Countries: Headquarters–Subsidiary Relationship

This article aims at providing further empirical evidence about the international activity of Italian small and medium enterprises (SMEs). In particular, the present contribution can be ascribable to the stream of research regarding the headquarters–subsidiary relationship. Focusing our attention on the subsidiary of Italian SMEs internationalized in Central and Eastern European countries (CEECs), we provide evidences about the main variables affecting their autonomy. Literature review provides us evidences of the fact that subsidiary autonomy is an extremely heterogeneous topic to investigate. Consequently, we decided to add to the quantitative analysis also a qualitative one. Through personal interviews with the Italian entrepreneurs and the managers of the local subsidiaries, we got a better and deeper insight into the evidences coming from the quantitative data.     

More than just a utensil: The influence of drinking straw size on perceived consumption

This research replicates and extends Wansink and colleagues' research on the effect of container size on actual consumption by examining the influence of medium size of consumption (straw size) on perceived consumption. Results from two studies show that participants who used a thin straw perceived their consumption as greater than those who used a thick straw, because straw size can lead to different perceptions of consumption time. Furthermore, sip size does not moderate the effect of straw size on perceived consumption.     

中国经济增长模式演进的就业效应

自20世纪90年代初期以来,中国经济从原来的劳动密集的增长模式转变为资本深化的增长模式。前一种增长模式能够实现产出和就业的双重增长,缺陷在于劳动报酬增长滞后于产出增长;后一种增长模式能够促进产出增长和劳动报酬的提高,缺陷是创造就业的能力表现不足。但从现实性来考虑,后一种模式比前一种模式更具可行性。     

Foundations of Technical Analysis: Computational Algorithms, Statistical Inference, and Empirical Implementation

Technical analysis, also known as 'charting,' has been a part of financial practice for many decades, but this discipline has not received the same level of academic scrutiny and acceptance as more traditional approaches such as fundamental analysis. One of the main obstacles is the highly subjective nature of technical analysis—the presence of geometric shapes in historical price charts is often in the eyes of the beholder. In this paper, we propose a systematic and automatic approach to technical pattern recognition using nonparametric kernel regression, and we apply this method to a large number of U.S. stocks from 1962 to 1996 to evaluate the effectiveness of technical analysis. By comparing the unconditional empirical distribution of daily stock returns to the conditional distribution—conditioned on specific technical indicators such as head-and-shoulders or double bottoms—we find that over the 31-year sample period, several technical indicators do provide incremental information and may have some practical value.     

Valuation of insurers’ contingent capital with counterparty risk and price endogeneity

This study develops a structural framework to value insurers’ contingent capital with counterparty risk (CR) and overcomes the problem of price endogeneity (PE) in the valuation model. Our results on the focal contingent capital instrument – catastrophe equity put option (CatEPut) – indicate that prices can be significantly overestimated without considering CR and be significantly underestimated without considering PE. This study also examines how CatEPuts affect the buyer’s probability of default (PD). Our results show that buying a CatEPut lowers the PD for high-risk insurers, but not necessarily so for low-risk insurers; however, without taking CR and PE into account, one may significantly overestimate the credit enhancement provided by the CatEPuts.     

When are contrarian profits due to stock market overreaction?

If returns on some stocks systematically lead or lag those ofothers, a portfolio strategy that sells 'winners' and buys 'losers'can produce positive expected returns, even if no stock's returnsare negatively autocorrelated as virtually all models of overreactionimply. Using a particular contrarian strategy we show that,despite negative autocorrelation in individual stock returns,weekly portfolio returns are strongly positively autocorrelatedand are the result of important cross-auto-correlations. Wefind that the returns of large stocks lead those of smallerstocks, and we present evidence against overreaction as theonly source of contrarian profits.     

Are corporates' target leverage ratios time-dependent?

This paper extends the stationary-leverage-ratio model to incorporate a time-dependent target leverage ratio. The theoretical hypothesis of the existence of a time-dependent target leverage ratio reflects the movement of a firm's initial target ratio toward a long-term target ratio over time. Using some simple scenarios about the time-dependence of the target leverage ratio, the numerical results show that the incorporation of the hypothesis into the stationary-leverage-ratio model is capable of producing term structures of probabilities of default that are consistent with some empirical findings. The results provide some evidences to support the hypothesis.     

Does Interindustry and Intraindustry Information Help Predict Financial Distress?

This study investigates whether and how the accounting ratios of peer firms within the same industry (the industry peers) or firms within the industry of their customers (the downstream peers) help improve the predictability of sample firm financial distress. We document that the Z‐score factors of the companies with high correlation in stock returns help predict financial distress. The results show that accounting‐based ratios of the industry peers and the downstream peers enhance the accuracy of early warnings of financial distress, especially when prior returns of peer firms are highly correlated with the sample firm.     

Labor market institutions and inflation volatility in the euro area

Despite having had the same currency for many years, EMU countries still have quite different inflation dynamics. In this paper we explore one possible reason: country specific labor market institutions, giving rise to different inflation volatilities. When unemployment insurance schemes differ, as they do in EMU, reservation wages react differently in each country to area-wide shocks. This implies that real marginal costs and inflation also react differently. We report evidence for EMU countries supporting the existence of a cross-country link over the cycle between labor market structures on the one side and real wages and inflation on the other. We then build a DSGE model that replicates the data evidence. The inflation volatility differentials produced by asymmetric labor markets generate welfare losses at the currency area level of approximately 0.3% of steady state consumption.
