Transaction costs and market efficiency: Evidence from commission deregulation

This study analyzes the impacts of explicit transaction costs on weak-form market efficiency within the context of the brokerage commission deregulation in Japan in October 1999, which led to lower commission rates across the market. Applying two alternative statistical tests to both daily and weekly data, we find that return randomness (unpredictability) increases significantly for stocks listed in Japan, but not for the Japanese stocks dually listed in the United States, which are immune to the deregulation. These results suggest an inefficiency loss or an efficiency gain in the Japanese equity market following the deregulation, insofar as randomness proxies for efficiency.     

Rent-seeking,promotion pressure and green economic efficiency: Evidence from China

Focusing on the quality and sustainability of urban economic development and using a panel dataset of 263 cities in China from 2004 to 2015, this paper regards each city as a production unit and uses the Epsilon-Based Measure approach to measure green economic efficiency by innovatively regarding labor, capital, land and energy as input factors, GDP as a desirable output, and environmental pollution emissions and land finance as undesirable outputs. Further, this paper examines the effect of rent-seeking on green economic efficiency with a fixed effects model and explores the role of promotion pressure in the relationship between rent-seeking and green economic efficiency with a panel threshold model. Our study finds that: (1) Rent-seeking exerts a significant negative impact on green economic efficiency. (2) Compared to areas of higher promotion pressure, the negative effect of rent-seeking on green economic efficiency is greater in areas facing lower promotion pressure. (3) The relationship among promotion pressure, rent-seeking and green economic efficiency differs in areas facing different “green” promotion pressure.     

A reexamination of the market efficiency hypothesis: Evidence from an electronic intra-day,inter-dealer FX market

Researchers acknowledge that the evidence of autocorrelation (price dependency) in daily/weekly asset returns provides no conclusive evidence against the market efficiency hypothesis since the holding period of actual speculative positions may be less than a day. Using a high frequency (up to one hundredth of a second), transaction-based, electronic foreign exchange (FX) brokerage data set, we show that dealers in this market tend to close their speculative positions in less than a minute. We provide evidence that there is a significant negative autocorrelation in the rate of return on DM/USD exchange rate. However, when we sample data at frequencies shorter than a minute, profits are infeasible for two reasons: (1) the structure of the autocorrelation pattern is not consistent enough; (2) the largest potential speculative profit derived from the autocorrelation pattern is smaller than the regulated tick size. Our results support the market efficiency hypothesis as dealers have evidently engaged potentially profitable speculation based on price dependency.     

Misvaluation comovement,market efficiency and the cross-section of stock returns: Evidence from China

In this study, we examine the relation between stock misvaluation and expected returns in China's A-share market. We measure individual stocks’ misvaluation based on their pricing deviation from fundamental values, following Rhodes-Kropf et al. (2005. J. Finan. Econ. 77 (3), 561) and Chang et al. (2013. J. Bank. Finance, forthcoming), and find that the measure has strong and robust return predictive power in the Chinese market. We further form a misvaluation factor and find that misvaluation comovement and systematic misvaluation exist in the Chinese market. A comparison of our results with those of Chang et al. (2013. J. Bank. Finance, forthcoming) reveals that the misvaluation effect is much stronger in the Chinese market than in the U.S market. This evidence is consistent with the notion that the Chinese market is much less efficient than the U.S. market. Finally, we show that the return predictive power of misvaluation has weakened since China launched its split-share structure reform in 2005, which could result from the fact that the reform helps to promote market efficiency.     

Interregional Migration and Thresholds: Evidence from Spain

We analyse the effects of labour market factors on interregional migration in Spain for the period 1988–2010. A basic theoretical framework is developed, suggesting that the effect of labour market variables on migration varies, depending on a certain threshold. The model implications are tested using a new approach based on the presence of endogenous thresholds. We show that Spanish interregional migration can be explained by labour market variables when the labour market conditions at the source region are unfavourable relative to those of the host region. We test the results for several migrant characteristics, such as citizenship, the age range, and return migration.

Fiscal policy and stock market efficiency: Evidence for the United States

This paper examines the extent to which fiscal policy actions affect the stock market's behavior for the US during 1968–2005. The findings are consistent with the hypothesis that past budget deficits negatively affect current stock returns thus suggesting that the market is inefficient with respect to information about future fiscal policy actions. One interpretation of this ‘disturbing’ result is that market participants do not place much faith on news about the budget deficits as they do not believe that deficits could adversely impact the stock market. Instead, what the market considers most important is news about monetary policy.     

Environmental Management Evolution: Empirical Evidence from Spain and Italy

This research is focused on a survey conducted among Spanish and Italian companies in order to define the environmental management evolution within firms. Through this survey, a number of maturity stages were defined and validated, and the identification of the relevant factors for each of the maturity stages was made. Survey results show that companies start with environmental management issues due to legislation requirements. Afterwards, firms go through a training phase, continuing with the systematization stage, then look for economic benefits through ecological improvements (ECO² stage) and finish with the eco‐innovation and leading green company stages. The survey has shown that the maturity stages have application in all types of industrial sector. These are useful for those firms that want to make progress in environmental matters, as it helps them to identify at which maturity stage they are and what are the factors that they need to take into account to move forward.

Work Recognition and Labor Productivity: Evidence from French Data

We empirically investigate whether labor productivity is related to work recognition. Using survey data about a large sample of French firms (N = 5309), we find that firms in which employees think their work is recognized are likely to report higher labor productivity, compared with firms where employees do not feel recognized. Our estimation results also suggest that labor productivity is strongly related to wages. Copyright © 2014 John Wiley & Sons, Ltd.     

Sharing Wealth: Evidence from Financial Ratios in Spain

Firms are managed on the basis of relationships between mutually involved groups, not only because of market forces, but also due to the influence that each group can exert over distribution decisions at a given moment in time. On the basis of a value added statement, it is possible to analyse the ability a firm has to reward all agents and to consider how the residual income is to be distributed. In this paper we set out to establish the tensions that arise between productive agents in the distribution of generated wealth. We carry out a time analysis of the movements between relationships that provide information on the distribution of that wealth, using data drawn from the Spanish Transport Equipment Manufacturing Industry. We propose a new multivariate dynamic linear model that is capable of analysing the joint evolution of the value added distribution ratios, with our particular objective being to throw light on the factors underlying this evolution. This analysis results in one single factor that explains 92.88 per cent of the total variation present in the residuals of the model.     

Marshallian labour market pooling: Evidence from Italy

This paper employs a unique Italian data source to take a comprehensive approach to labour market pooling. It jointly considers many different aspects of the agglomeration — labour market relationship, including turnover, learning, matching, and hold up. It also considers labour market pooling from the perspective of both workers and firms and across a range of industries. Overall, the paper finds some support for theories of labour market pooling, but the support is weak. Specifically, there is a general positive relationship of turnover to local population density, which is consistent with theories of agglomeration and uncertainty. There is also evidence of on-the-job learning that is consistent with theories of labour pooling, labour poaching, and hold up. In addition, the paper provides evidence consistent with agglomeration improving job matches. However, the labour market pooling gains that we measure are small in magnitude and seem unlikely to account for a substantial share of the agglomeration benefits accruing to Italian workers and firms.     

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.     

The migration response to local labour market shocks: Evidence from EU regions during the global economic crisis

The global economic crisis has strongly affected Europe's economic geography. This study investigates the role of local labour market disparities in determining regional net in‐migration rates. While only a weak link is detected in the precrisis period, the local labour market context of migration grows significantly stronger during the crisis. Decompositions of the estimation results show that changes in migration rates are firstly a result of widened disparities across European regions throughout the crisis. However, also behavioural adjustment processes occur, e.g. an orientation of migrants towards urban areas and away from regions with persistently high long‐run unemployment rates.     

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.

EVT and tail-risk modelling: Evidence from market indices and volatility series

Value-at-Risk (VaR) has become the universally accepted risk metric adopted internationally under the Basel Accords for banking industry internal control, capital adequacy and regulatory reporting. The recent extreme financial market events such as the Global Financial Crisis (GFC) commencing in 2007 and the following developments in European markets mean that there is a great deal of attention paid to risk measurement and risk hedging. In particular, to risk indices and attached derivatives as hedges for equity market risk. The techniques used to model tail risk such as VaR have attracted criticism for their inability to model extreme market conditions. In this paper we discuss tail specific distribution based Extreme Value Theory (EVT) and evaluate different methods that may be used to calculate VaR ranging from well known econometrics models of GARCH and its variants to EVT based models which focus specifically on the tails of the distribution. We apply Univariate Extreme Value Theory to model extreme market risk for the FTSE100 UK Index and S&P-500 US markets indices plus their volatility indices. We show with empirical evidence that EVT can be successfully applied to financial market return series for predicting static VaR, CVaR or Expected Shortfall (ES) and also daily VaR and ES using a GARCH(1,1) and EVT based dynamic approach to these various indices. The behaviour of these indices in their tails have implications for hedging strategies in extreme market conditions.     

Seasonality in asset returns: Evidence from the gold market

In this paper we test monthly mean daily returns to gold over the period January 1975 to December 1984 against three definitions of seasonality. Weak evidence exists for seasonality under the second of the three definitions. However, this is not prima facie evidence of market inefficiency, as the pattern is consistent with seasonality in Eurodollar interest rates reported by other authors. Differences in the time pattern of returns between on- and off-shore rates raises further questions.     

Globalisation,industrial efficiency and technological sovereignty: Evidence from Brazil

Since the end of the 1980s the Brazilian economy has become increasingly exposed to the forces of globalisation. As trade and market liberalisation have progressed, so the industrial sector has been obliged to undergo a substantial transformation. This paper examines the nature of this transformation focusing on three key themes: productive efficiency, industrial restructuring and technological sovereignty. While, at least in terms of productivity and cost competitiveness, efficiency has undoubtedly increased, the evidence concerning the impact of liberalisation on technological sovereignty is somewhat more ambiguous. However, it is clear that, in many instances the reliance of the Brazilian industrial sector on foreign sources of technology has markedly increased. This, in turn raises a number of troubling issues, not least the ability of emerging market economies to hold on to established areas of technological competence as globalisation continues to unfold.     

Labor market flexibility and poverty dynamics

The past two decades have witnessed a rapid growth in flexible work arrangements that, in some instances, could expose workers to a higher poverty risk via limited job stability, few advancement opportunities, and low wages. Nowhere in the world has this increase in flexible work arrangements being more evident than in Spain, where about a third of the wage and salary workforce holds fixed-term contracts. Using Spanish panel data and maximum-likelihood binary models that account for state dependence and unobserved heterogeneity, we examine the poverty implications of past and present temporary employment. Our findings suggest that fixed-term contracts are linked to a greater poverty exposure among women and older men relative to open-ended contracts. Furthermore, this greater poverty exposure can last several years due to feedback effects operating via job instability or via the transition to work statuses characterized by higher poverty hazards. Finally, the adverse impact of temporary employment is linked to the short duration of some contracts, thus signaling the importance of work attachment.     

Governance practices and agency cost in emerging market: Evidence from India

In this study, we examine whether governance practices brings down agency cost. We find that board size, board attendance, and CEO duality are important governance characteristics that influence the agency cost. We also bring out systematic differences in governance practices of the business group affiliated firms and stand‐alone firms. Larger board and proportion of independent director helps in reducing the agency cost for group affiliated firms supporting monitoring hypothesis. On the other hand, the governance structure of stand‐alone firms supports commitment hypothesis where we observe that board busyness and CEO duality help in reducing the agency cost.
