Information flows within and across sectors in Chinese stock markets

We examine the patterns of information flows within and across sectors of the two Chinese stock exchanges in Shanghai and Shenzhen during 1994–2001. Using the generalized forecast error variance decomposition, we find a high degree of interdependence, indicating that the sectors are highly integrated and sector prices reflect information from other sectors. Industry is the most influential sector in both exchanges, while Finance in Shenzhen is the least integrated with other sectors. Implications of the findings for investors and policymakers are also discussed.     

Non-linear and non-symmetric exchange-rate adjustment: Evidence from medium- and high-inflation countries

This paper analyses a model of non-linear exchange rate adjustment that extends the literature by allowing asymmetric responses to over- and under-valuations. Applying the model to Greece and Turkey, we find that adjustment is asymmetric and that exchange rates depend on the sign as well as the magnitude of deviations, being more responsive to over-valuations than undervaluations. Our findings support and extend the argument that non-linear models of exchange rate adjustment can help to overcome anomalies in exchange rate behaviour. They also suggest that exchange rate adjustment is non-linear in economies where fundamentals models work well.     

Discrimination in rental markets: Evidence from Norway

This paper examines discrimination in the rental housing market. We analyze a rich data set on rental contracts from Norway. We find that tenants born abroad pay a statistically significant and economically important premium for their dwelling units after controlling for a comprehensive set of apartment, individual and contract specific covariates. Moreover, we find that the premium is largest for tenants of African origin. Finally, Norwegians whose parents were born abroad also face a statistically significant and economically important rental premium that is directly comparable to the premium paid by tenants born abroad.     

Time-frequency connectedness of crude oil,economic policy uncertainty and Chinese commodity markets: Evidence from rolling window analysis

This article investigates the time–frequency connectedness of economic policy uncertainty (EPU), WTI crude oil and Chinese commodity markets during the period between 2004 and 2020. Rolling window wavelet vector autoregression and connectedness networks are developed to evaluate the time-varying characteristics of the connectedness. The empirical results are as follows: First, the total connectedness between EPU, oil and commodities becomes stronger as the time scale increases. Second, the net connectedness of EPU and WTI in the system is positive, indicating that EPU and WTI are contributors to information and will affect financial markets across time scales. Third, the connectedness remains at a high level during financial crises across all scales, and the contribution of EPU and crude oil to commodities increases significantly. Specifically, compared with other commodity sectors, grains are greatly affected by EPU under the condition that the energy sector is seriously affected by crude oil. Overall, investors and policy makers should consider connectedness in terms of time and frequency when making a decision.     

Financial innovation and bank behavior: Evidence from credit markets

This paper investigates whether, and through which channel, the active use of credit derivatives changes bank behavior in the credit market, and how this channel was affected by the crisis of 2007–2009. Our principal finding is that banks with larger gross positions in credit derivatives charge significantly lower corporate loan spreads, while banks׳ net positions are not consistently related to loan pricing. We argue that this is consistent with banks passing on risk management benefits to corporate borrowers but not with alternative channels through which credit derivative use may affect loan pricing. We also find that the magnitude of the risk management effect remained unchanged during the crisis period of 2007–2009. In addition, banks with larger gross positions in credit derivatives cut their lending by less than other banks during the crisis and have consistently lower loan charge-offs. In sum, our study is suggestive of significant risk management benefits from financial innovations that persist under adverse conditions – that is, when they matter most.     

Loss reserving behaviour in insurance markets: Evidence from Mauritius

This study examines determinants of loss reserves among a sample of 14 general insurance companies in Mauritius from 2008 to 2015. The paper documents evidence that on average, technical reserves account for 45.41% of total assets, made of 19.79% in unearned premiums and 25.62% in outstanding claims. Using panel regression techniques, the findings suggest that general insurers manipulate their earnings through reserve provisions to smooth income and tax considerations. In addition, underwriting risk and reinsurance increases technical reserves, whereas market concentration induces high provisioning for outstanding claims. Policy recommendations for industry regulations are discussed.     

Index futures trading and stock price volatility: Evidence from Denmark and France

This study uses an EGARCH methodology to investigate the impact of index futures trading on the price volatility of two European stock markets. The results show that index futures trading has changed the distribution of stock returns in Denmark and France, however, it has not increased stock price volatility. There is evidence that futures trading has dampened stock price fluctuations in France. The results further show that stocks in Denmark and France exhibit strong volatility persistence and asymmetry, especially during the post-futures period.     

Evidence of information transmission across currency futures markets using frequency domain tests

In this article, I examine the returns and volatility spillovers in the currency futures market incorporating the recently developed frequency domain tests. Such analysis allows differentiating between permanent (long-run) and transitory (short-run) linkages among the currency futures markets by investigating the causality dynamics at low and high frequencies respectively. I detect significant informational linkages between USD, EUR, GBP and JPY futures contracts in the Indian currency futures market. Evidence of innovations from USD futures market to other markets is the most significant for returns spillover and for volatility spillover, EUR is found to be the most significant compared to other currency futures contracts. The results would have implications for the market participants and policymakers.     

Odds-setting efficiency in gambling markets: Evidence from the PGA TOUR

This paper describes the gambling market for PGA TOUR events for the 2002 season. The extent to which the odds predict the outcome is examined, illustrating how much information is captured in the odds and whether there are any identifiable biases in the odds. The overall implied profit to the casino is calculated as well as the returns to several naive betting strategies. By splitting the sample based on whether or not Tiger Woods is in the tournament, a “Tiger Woods effect” or a “thin market versus thick market effect” can be examined. On the whole, efficient markets propositions hold up, but the overwhelming share of the variation in the tournament outcome remains unexplained.     

Liquidity and asset pricing: Evidence from the Chinese stock markets

We introduce a novel two-factor model, incorporating market and liquidity factors, which outperforms the CAPM and Fama–French factor models when applied to stock market returns in Shanghai and Shenzhen over 2000–2019. We compute the liquidity factor as the return on a liquidity-mimicking portfolio, which we construct simultaneously using two measures of liquidity (one of them capturing liquidity’s trading-quantity dimension, and the other associated with its price-impact dimension). Unlike the CAPM and Fama–French factor models, the advocated two-factor model is able to account for numerous return anomalies, such as size, book-to-market ratio, earnings-to-price ratio, cash-flow-to-price ratio, return-on-equity, and volatility. The model’s performance is similar when applied separately to the Shanghai and Shenzhen stock markets. Furthermore, it fares similarly over the 1994–2004 and 2005–2019 sub-periods. This result is somewhat surprising, because liquidity seems likely to have been substantially lower over 1994–2004, as the Chinese markets were noticeably smaller, and the critical market reform aimed at eliminating non-tradable shares by the end of 2006 did not occur until 2005.     

Asset pricing for inefficient markets: Evidence from China and India

Over last four decades, evidence of market inefficiencies has been widely documented by several scholars for all major stock markets in the globe. Chinese and Indian markets are not exempt. Inefficiencies in these markets are described by many authors as roots of all mispricing. Mispricing might be the outcome of application of familiar asset pricing models which may mislead an investor into adopting inappropriate policies for his new investments or for reallocating his old investments. In an alternative approach, we propose a transformation on original market returns in the objective of relaxing the strong assumption of market efficiency behind application of an asset pricing model. This modification will widen the scope of rational models on asset pricing ranging from an efficient to an inefficient market.     

Commodity-price volatility and macroeconomic spillovers: Evidence from nine emerging markets

The recent decade has witnessed wild swings in global commodity prices, with large increases preceding the Global Financial Crisis and steep declines following the crash. Many emerging markets find themselves destabilized by these fluctuations, not only when price increases lead to currency appreciations and reduced competitiveness, but also when price decreases cause capital outflows and deteriorations in the balance of payments. This study examines the volatility processes of six major commodity prices, before applying Multivariate GARCH analysis to examine spillovers among important commodity prices and output, exchange rates, interest rates and inflation in major emerging markets. While each commodity and each country behaves differently, we find that Chile is most closely tied to the copper price, and Indonesia to oil and tin, while neighbors such as Brazil and the Philippines are less affected. Perhaps surprisingly, Russia is found to be highly insulated from fluctuations in world oil prices.     

Perceptions of economic insecurity: Evidence from Russia

Economic insecurity is an inherent characteristic of the transition from a planned economy to a market-oriented economy and workers’ assessments of their economic insecurity have direct consequences not only for their happiness/well-being, but also on consumption and saving behavior. This study utilizes data from the nationally representative Russian Longitudinal Monitoring Survey to study perceptions of economic insecurity among workers in both rural and urban settlements. Analyzing three measures of perceived economic insecurity, we find that perceptions of insecurity were higher when economic conditions were deteriorating (1995–1998), and lower when economic conditions had stabilized (2000–2004). While perceived insecurity varies substantially by worker characteristics–those with less education, women, and unskilled and semi-skilled manual workers feel most vulnerable–, differences in observed characteristics explain a relatively small part of the ruralurban perceptions gap; other factors, such as different rates of economic recovery in rural and urban locales are also important. Individual well-being and household consumption tend to be lower when concerns about economic insecurity are present.     

Arbitrage concepts under trading restrictions in discrete-time financial markets

In a discrete-time setting, we study arbitrage concepts in the presence of convex trading constraints. We show that solvability of portfolio optimization problems is equivalent to absence of arbitrage of the first kind, a condition weaker than classical absence of arbitrage opportunities. We center our analysis on this characterization of market viability and derive versions of the fundamental theorems of asset pricing based on portfolio optimization arguments. By considering specifically a discrete-time setup, we simplify existing results and proofs that rely on semimartingale theory, thus allowing for a clear understanding of the foundational economic concepts involved. We exemplify these concepts, as well as some unexpected situations, in the context of one-period factor models with arbitrage opportunities under borrowing constraints.     

Labor market rigidities and economic efficiency: Evidence from Spain

In the 1990s, Spain approved two labor reforms aimed at reducing the unemployment level and its volatility. Overall, these reforms involved two measures designed to induce firms to meet their labor needs via adjustment of permanent positions: restricting the use of temporary workers and reducing the amount of severance payments. This paper empirically assesses the impact of these reforms on the allocative efficiency of the labor input employing Petrin and Sivadasan's (2011) value of the marginal product-marginal cost gap methodology. We find a statistically significant increase in within-firm permanent labor gaps following the reforms. These results suggest that restrictions on the use of temporary workers (increasing the probability of hiring fragile workers for permanent positions), when coupled with uncertainty about enforcement of reduced severance payments, could more than offset the reduction in severance payments; hence, the net effect of the reforms could be to increase adjustment costs for permanent positions.     

Entrepreneurship and economic growth: Evidence from emerging and developed countries

This paper presents an extension to the economic growth model developed by Wong, Ho, and Autio (2005 Autio, E. 2005. 2005 report on high-expectation entrepreneurship, Toronto: GEM Consortium.  [Google Scholar]), to reflect differences in the economic effects of opportunity and necessity-based entrepreneurship in both emerging and developed countries. Data from 44 countries for the years 2004 and 2005, as collected by Global Entrepreneurship Monitor (GEM) research and Global Competitiveness Report (GCR) research, are used to identify predictors of GDP growth for emerging and developed nations. The GEM data are used to determine the effect of different types of entrepreneurship on GDP growth. The GCR data operationalize additional control variables suggested by three economic growth theories: new economic geography, endogenous growth theory and national systems of innovation. This contribution to the literature suggests that, in developed countries, a significant portion of economic growth rates can be attributed to high-expectation entrepreneurs exploiting national investments in knowledge creation and regulatory freedom. However, in emerging countries this effect is absent. It is hypothesized that a threshold exists for entrepreneurs to gain access to the formal economy, below which entrepreneurial contributions act through informal mechanisms.     

Insider trading: Regulation, securities markets, and welfare under risk aversion

I analyze in this article the impact of insider trading regulation (ITR) on a securities market and on social welfare, and argue that the imposition of ITR forces a reallocation of wealth and risk that decreases social welfare. Three reasons explain this result: First, ITR increases the volatility of securities prices; second, it worsens the risk sharing among investors; and, third, it diverts resources from the productive sector of the economy. Further, although I formally establish conditions under which ITR makes society better off, I argue that those conditions are not useful to justify the imposition of this regulation.     

Servitization across countries and sectors: Evidence from world input-output data

This paper uses the supply tables underlying WIOT data to explore the provision of services by manufacturing. The service shares differ substantially across countries and sectors, while they remain largely stable over time. A latent class analysis assigns broadly defined manufacturing sectors to economy-wide growth models, differentiating between service- and manufacturing-driven models in catching-up and developed economies. Servitization increases with labor productivity. The service intensities in the sectoral production mix are lower in countries with higher manufacturing shares. This holds for both catching-up and developed economies. However, servitization is largely unrelated to productivity and employment growth. We therefore argue that the degree of servitization is contingent on and an attribute of the respective economic model in which a sector operates.     

Illicit drug markets and economic irregularities

Markets for illicit drugs present an interesting case study for economics, combining non-standard characteristics such as addiction and product illegality. One response has been to argue the generality of economic principles by suggesting that they apply even in the extreme case of markets for addictive substances, e.g., by showing that demand for illicit goods is responsive to price [1] [Reframing health behavior change with behavioral economics. Hillsdale, NJ:Lawrence Earlbaum Associates; 2000. p. 89-111.] and even by modeling addiction as rational [2] [J Political Econ 1988;96:675-700]. This paper sketches examples of an alternative reaction, focusing on idiosyncrasies of drug markets that might plausibly create counter-intuitive effects, including supply curves that slope downward because of enforcement swamping and/or a good serving as the only available store of wealth for its producer, demand reduction programs that increase demand, and consumption by “jugglers” possibly increasing rather than decreasing as prices rise. This analysis yields non-obvious policy recommendations; for example, source country control programs should concentrate on growing regions with a healthy banking sector.
