Liquidity commonality in order-driven trading: evidence from the Athens Stock Exchange

We examine the presence of liquidity commonality in the order-driven Athens Stock Exchange (ASE). Unlike the majority of liquidity commonality studies that focus on the bid–ask spread, our analysis extends deeper in the Limit Order Book, providing insight on the price impact of both small and large trades. We utilize a 6-month FTSE/ATHEX-20 intraday data set to estimate the liquidity factor model of Chordia et al. (2000). To this end, we conduct single-equation analysis as well as panel data analysis with the use of two-way clustered errors, correcting for simultaneous firm and time correlations. Moreover, we apply standard principal component analysis on stock liquidities to extract the marketwide liquidity component. We find that liquidity commonality is low at the bid–ask spread, whereas it increases deeper in the book; consequently, large traders face liquidity risks associated with both individual stock and marketwide illiquidity. Moreover, our empirical evidence hints that liquidity commonality is asynchronous, suggesting that the ASE trading process includes various levels of information speed. Our analysis contributes to the understanding of liquidity commonality in order-driven trading, especially in emerging markets like the ASE where trading activity is limited and information speed is low.     

Spatial and economic patterns in life expectancy among US States

This study investigates the determinants of gender-specific life expectancy across US states over the period 1995–2007. We employ a production function specification where life expectancy depends on health expenditure, income, education and lifestyle variables, allowing for spatial effects. Empirical results suggest that education attainment and health expenditure are the main factors behind improving longevity, whereas smoking bears a strong negative influence. For robustness purposes, we also use health spending as well as education criteria, apart from geographical ones to model interstate spillovers. In the former case, states with similar health expenditure are ‘neighbors’ and affect positively the life expectancy process. If education is applied instead of health spending together with geographic proximity, the spatial correlation is insignificant, i.e. education ‘neighbors’ do not affect life expectancy. Our findings do not imply significant gender differences regarding health production. The results suggest that health care policy will have to focus on wider economic and social considerations, like education and lifestyle changes, except medical care provision in order to exploit the full potential for life expectancy improvements of the US population.     

Environmental performance and plant closure

This study uses a sample of plant closings as the testing stage to examine the financial consequences of variant environmental performance records and stakeholder pressure levels. It compares 117 manufacturing facilities closing down between 1998 and 2000 to 351 facilities surviving through this period, along four measures of environmental performance. It shows that in the ten years prior to closure, closing facilities reduce their toxics emissions relatively more and incur somewhat stronger community and regulatory pressures than surviving ones. The results persist through alternative versions of the model and suggest that the environmental performance of closing facilities is at least as good as that of surviving ones. The mix of environmental practices of closing facilities differs from that of surviving ones with the former engaging in significantly less recycling of waste than the latter. Closing facilities focus more on end-of-pipe measures while surviving ones engage in more pro-active strategies, consistent with evidence in the literature of a positive relation between pro-active environmental practices and performance. Stakeholder pressures, in some cases (e.g., in pollution intensive industries), may be associated with unrecoverable costs to facilities, including closure, depending on the environmental management choices of the facilities.     

Mentoring and expressive network resources: their relationship with career success and emotional exhaustion among Hellenes employees involved in emotion work

Although mentoring has been identified as an important career resource for protégés in the Anglo-Saxon cultural cluster, pertinent research in other cultures is still scarce. The relationship of mentoring and expressive network resources with protégés' career success and emotional exhaustion was investigated in a sample of 104 Hellenes (Greek) bank employees performing frontline service jobs. The number of mentors that respondents reported they have had was related to their extrinsic career success. However, currently having a mentor was not related to intrinsic career success and was marginally related to emotional exhaustion. In contrast, the amount of expressive network resources was strongly related to both intrinsic career success and emotional exhaustion. The results are discussed with respect to extant research, the national cultural context of the study and the cross-cultural transferability of human resource systems. The general tentative conclusion is that relationships with mentors and expressive network resources appear to be important resources for employees across cultures, but the relative potency of their benefits is influenced by the national cultural characteristics.     

Pollution, Capital Mobility and Tax Policies with Unemployment

In this paper we highlight aspects related to the links among unemployment, international capital mobility, and tax policies in a small open developing economy. Without international capital mobility, the joint optimal trade and environmental policies require a zero tariff and an emission tax lower than the Pigouvian tax. With international capital mobility and a capital tax (subsidy), the optimal emission tax rate is smaller (larger) compared to the rate when capital is untaxed. When both the emission tax and the capital tax/subsidy are jointly chosen optimally, then the optimal policy on capital is a lower subsidy, or even a tax, compared to the standard capital subsidy of the no pollution case.     

CONVERGENCE AND ECONOMIC PERFORMANCE IN GREECE: EVIDENCE AT REGIONAL AND PREFECTURE LEVEL

The purpose of this paper is to test regional convergence and to investigate interregional disparities in terms of per capita income in Greece. The novelty of our study lies in the use of a disaggregated dataset for an extended time period (1971–2003) at two regional levels (NUTS II & NUTS III). Our results indicate that there is β convergence between prefectures but not among regions, while no evidence of σ convergence is found at both regional levels. Also, the GDP geographic concentration and population density have a negative impact on growth, which outweighs the positive growth effect of population geographic concentration and GDP spatial inequality. Thus, policies aiming at the decentralization of economic activity in Greece might enhance growth and regional equality simultaneously. Finally, we do not find economic dualism across geographic areas; however, rich prefectures seem to converge faster than poor ones.     

Punishment and counter-punishment in public good games: Can we really govern ourselves?

A number of experimental studies have shown that the opportunity to punish anti-social behavior increases cooperation levels when agents face a social dilemma. Using a public good experiment, I show that in the presence of counter-punishment opportunities cooperators are less willing to punish free riders. As a result, cooperation breaks down and groups have lower earnings in comparison to a treatment without punishments where free riding is predominant. Approximately one quarter of all punishments are retaliated. Counter-punishments appear to be driven partly by strategic considerations and partly by a desire to reciprocate punishments.
