Cost structure,technological change,and productivity growth in the greek banking sector

This paper first empirically investigates the cost structure of the Greek banking sector. Secondly, it provides measures of economies (diseconomies) of scale and quantifies technical change and its sources. Finally, this paper measures total factor productivity growth and identifies its sources. Bank production is presented with two different approaches (the intermediation and the production approach) which are used to specify a translog cost function. The two different translog cost models are estimated through the full information maximum likelihood method of estimation on pooled time series and cross sectional data. The results obtained are not significantly affected by model specification. Both models indicate significant economies of scale and negative annual rates of growth in technical change and in total factor productivity.     

Energy productivity convergence: new evidence from club converging

The goal of this study is to explore the convergence of energy productivity across 31 countries from 1972 to 2012 by using the convergence club algorithm developed by Phillips and Sul (2007). The empirical results lead to the rejection of full convergence and to the presence of a certain number of clubs. The transitional curves, however, indicate that over the long run energy productivity tends to converge, indicating the strong attempts of the countries under investigation to adopt energy policies that eventually contribute to a convergence pattern.     

Political and Institutional Factors in the Convergence of International Equity Markets: Evidence from the Club Convergence and Clustering Procedure

In this study the new panel convergence methodology developed by Phillips and Sul (2007) is employed to explore the convergence dynamics of international equity markets and determine whether political and institutional factors can explain convergence or divergence patterns across international equity markets. The empirical findings suggest that international equity markets do not form a homogeneous convergence club. Seven specific political and institutional factors are used to explain such divergent behavior. The empirical analysis documented specific factors, i.e. democratization, unemployment benefits, and public expenditure on pensions, which seem capable of explaining such a heterogeneous divergent pattern among the equity markets under study.     

Nonlinearities between oil spot and futures markets： Evidence from intraday data

This paper builds on the literature of the relationship between oil spot and futures prices from the NYNEX market, both in their means and in their conditional volatilities, to investigate whether the association is linear or not. The novelty of this work is based on intraday data from both markets. The empirical findings indicate the presence of nonlinearities both in means and conditional volatilities. Moreover, non-linear causality estimations both in means and in volatilities reveal the presence of bi-directional causality, a fact that provides additional support to the hypothesis that both markets are driven by the same information sets.     

Health Expenses: Evidence from the Club Clustering Approach

This paper explores convergence of real health expenses across the Indian states. The new panel convergence methodology developed by Phillips and Sul (Econometrica 75:1771–1855, 2007) is employed. The empirical findings suggest that these states form distinct convergent clubs, exhibiting considerable heterogeneity in the underlying health expenses patterns.     

Measuring Exchange Market Pressure and the Degree of Exchange Market Intervention for the Greek Drachma

This paper presents exchange market pressure and intervention indices than can be applied as tools for policy analysis in the case of Greece. A small open economy model is presented that helps to assess Greek exchange rate policy, within a framework characterized for a strong preference to eliminate excessive exchange rate volatility to meet the Maastricht criteria of low inflation and a fixed domestic currency.

Debt uncertainty and economic growth: evidence from five highly indebted Eurozone countries

The goal of this study is to examine the relationships between economic growth and debt uncertainty by applying the threshold generalized autoregressive conditional heteroscedasticity modelling methodology in five Eurozone countries spanning the period 2001–2013. The results document that during the European fiscal crisis period, debt uncertainty exerts a significant negative effect on economic growth across all five Eurozone countries that experienced the deterioration of their fiscal positions.     

Mean spillover effects in agricultural prices: Evidence from changes in policy regimes

This paper investigates the behavior of input, output, and consumer food prices under two different policy regime periods, before and after the reformulation of the Common Agricultural Policy (CAP) occurred in May 1992. The findings, through Granger causality tests, support a different behavior in terms of the transmission from the input level to the consumer level and vice versa. This transmission occurs through the output level only for the post-CAP reformulation period, while it occurs in a direct manner over the first period. The results imply that the decrease of agricultural output prices, due to lower minimum support prices following the reformulation of the CAP, is transmitted through the output price mechanism in both input and consumer food markets.     

Asset pricing and foreign exchange risk

According to the International Capital Asset Pricing Model (ICAPM), the covariance of assets with foreign exchange currency returns should be a risk factor that must be priced when the purchasing power parity is violated. The goal of this study is to re-examine the relationship between stock returns and foreign exchange risk. The novelties of this work are: (a) a data set that makes use of daily observations for the measurement of the foreign exchange exposure and volatility of the sample firms and (b) data from a Eurozone country.The methodology we make use in reference to the estimation of the sensitivity of each stock to exchange rate movements is that it allows regressing stock returns against factors controlling for market risk, size, value, momentum, foreign exchange exposure and foreign exchange volatility. Stocks are then classified according to their foreign exchange sensitivity portfolios and the return of a hedge (zero-investment) portfolio is calculated. Next, the abnormal returns of the hedge portfolio are regressed against the return of the factors. Finally, we construct a foreign exchange risk factor in such manner as to obtain a monotonic relation between foreign exchange risk and expected returns.The empirical findings show that the foreign exchange risk is priced in the cross section of the German stock returns over the period 2000-2008. Furthermore, they show that the relationship between returns and foreign exchange sensitivity is nonlinear, but it takes an inverse U-shape and that foreign exchange sensitivity is larger for small size firms and value stocks.
