What drives the banks' diversification decision? A dynamic nonlinear panel data approach

This paper empirically determines the drivers of functional diversification decision for 365 banks set in selected Middle East and North Africa (MENA) countries over 1988–2015. For this purpose, we use a dynamic nonlinear panel data model. Our findings reveal that both market share and financial intermediation stratify the diversification decision for the whole MENA sample. Splitting the sample shows that the risk‐adjusted profitability and the loan loss provision ratio exert a major influence over the diversification indicator for Gulf Cooperation Council (GCC) banks, whereas the net interest margin ratio, the bank market share, and financial intermediation are the major drivers of the strategic decision for the remaining non‐GCC banks.     

Is there a unit root in the inflation rate? Evidence from sequential break and panel data models

Using sequential trend break and panel data models, we investigate the unit root hypothesis for the inflation rates of thirteen OECD countries. With individual country tests, we find evidence of stationarity in only four of the thirteen countries. The results are more striking with the panel data model. We can strongly reject the unit root hypothesis both for a panel of all thirteen countries and for a number of smaller panels consisting of as few as three countries. The non-rejection of the unit root hypothesis for inflation is very fragile to even a small amount of cross-section variation. © 1997 John Wiley & Sons, Ltd.     

Governance infrastructure and indebtedness of African countries: Do regional blocs matter?

Motivated by the intermediating role of good institutions in enabling growth via external debt financed investment and the touted promise of regional integration for Africa's growth prospect, we use data on 37 countries, over the period 2002–2010, to explore the governance institutions—external indebtedness nexus in Africa, at the regional bloc level. We find a robust negative relation between governance institutions and external indebtedness in East & Horn of Africa, Central Africa and Southern Africa; and unclear relationships in North and West Africa regions. Importantly, these baseline results are robust to the consideration of debt write-offs, natural resource rents, and endogeneity. Further, we find that geographic, economic and cultural factors of proximity, intra-regional activity, shared official language, legal origin and dominant religion, largely explain the commonality of Africa's regional blocs of countries. These and other results of the study can support potential external debt management strategy that leverages effective governance institutions and enhanced regional economic integration.     

Employer preferences,collective agreements and the Australian resources sector: a paradox of limited commodification?

There is a commonly held view that firms in high‐wage/skill‐intensive sectors will tend to provide wages and working conditions that are above market‐clearing levels. This article empirically examines this claim by analysing the content of all collective agreements concluded in the resource sector in Australia after the enactment in 2006 of the Workplace Relations Amendment (Workchoices) Act. This legislation gave employers unprecedented ability to place downwards pressure on employee entitlements. In the resource sector, however, the quantitative results indicate that firms maintained, in the main, substantive standards but used extensively key regulatory provisions to gain an unprecedented level of control over both functional and numerical flexibility.     

Do house prices reflect fundamentals? Aggregate and panel data evidence

We investigate whether recently high and consequently rapidly decreasing U.S. house prices have been justified by fundamental factors such as personal income, population, house rent, stock market wealth, building costs, and mortgage rate. We first conduct the standard unit root and cointegration tests with aggregate data. Nationwide analysis potentially suffers from problems of the low power of stationarity tests and the ignorance of dependence among regional house markets. Therefore, we also employ panel data stationarity tests which are robust to cross-sectional dependence. Contrary to previous panel studies of the U.S. housing market, we consider several, not just one, fundamental factors. Our results confirm that panel data unit root tests have greater power as compared with univariate tests. However, the overall conclusions are the same for both methodologies. The house price does not align with the fundamentals in sub-samples prior to 1996 and from 1997 to 2006. It appears that the real estate prices take long swings from their fundamental value and it can take decades before they revert to it. The most recent correction (a collapsed bubble) occurred around 2006.     

Domestic Violence and Football in Glasgow: Are Reference Points Relevant?

A growing body of evidence suggests that people exhibit loss aversion – the displeasure from suffering a loss is larger than the pleasure enjoyed from an equivalent‐sized gain – and that expectations are important in determining what is perceived as a loss. Recent research suggests that disappointing results in sporting fixtures relative to prematch expectations play an important role in triggering domestic violence (Card and Dahl, 2011), consistent with the idea of loss aversion around expectations‐based reference points. This paper seeks to investigate whether such behaviour is exhibited by football fans in Glasgow by looking at the relationship between match outcomes relative to expectations and levels of domestic violence using a data set that contains every domestic violence incident in Glasgow over a period of more than eight years. Whilst we find that when the ‘Old‐Firm’ Glasgow rivals Celtic and Rangers play there are large increases in domestic violence (regardless of the outcome of the match), in other matches disappointing results relative to expectations are not linked to increased domestic violence, except when those matches occur at the very end of the season where the title is still being contended.     

What are the main explanations of occupational diseases and accidents at work in the agricultural sector? A panel analysis for Italian regional data

The aim of this paper is to investigate the causes of occupational diseases and accidents at work (ODA) in the Italian agricultural sector. To this end, we proceed with a two-stage analysis of Italian regional data for the period 1976–2004. The first phase of the analysis shows that in the Italian agricultural sector productivity Granger-causes ODA, and not vice versa. The results of the econometric estimates in the second stage of the analysis show that an increase in “productivity pressure” (associated with an increase in production rhythms) will produce, in the long run, an increase in accidents on less serious ODA (or temporary ODA); the same effect will not be observed on the more serious ODA (or permanent ODA). We verify how pro work legislation reduces ODA and how this effect is strengthened in the long-run. In addition, we observe that in the long-run the increase in the “pressure on workers” (associated with a high unemployment rate and a high probability of being fired) is the main cause of the increase in less and more serious ODA.     

Urban effects on participation and wages: Are there gender differences?

This paper estimates participation and wage equations using panel data from the United Kingdom to explore gender differences in urban wage and participation premiums. The results suggest a small but economically significant urban participation premium for women but none for men. Results from the wage estimations suggest that after controlling for sample selectivity, observed and unobserved heterogeneity, the urban premium is larger for women. This wage premium is also larger for married or cohabiting women relative to others. There is also evidence of higher urban returns to experience for men and lower urban wage depreciation for both men and women.     

Geometry or poetry? Issues of methods and techniques in regional research

This article begins with the assumption that the research and study of geographical, historical, socio-economic and cultural factors of a local community are prerequisites for intervention or developmental policies. Based on the views of Descartes and Hamann, it then goes on to look at the suitability of the methods, tools and techniques a researcher needs to use today in order to get a complete picture. A positive approach of social phenomena claims that social structures decisively affect an individual’s thought and action, and therefore focuses on the study of external factors. In contrast, an interpretative approach aims at understanding the meanings and motives that govern an individual’s life and behavior. The author concludes that research on both macro and micro levels are necessary for the understanding of social phenomena in a local society and the use of methodological pluralism (both quantitative and qualitative methods) is necessary for effective research as it takes into consideration the weight of history and allows the understanding of those factors which govern people’s lives and determine their behavior and interaction.     

Wages and prices: Are workers fully compensated for cost of living differences?

This paper investigates the equilibrium relationship between wages and prices across labor markets. Of central interest is the extent to which workers receive higher wages to compensate for differences in the cost of living. According to the spatial equilibrium hypothesis, the utility of homogenous workers should be equal across labor markets. This implies that controlling for amenity differences across areas, the elasticity between wages and the general price level across areas should equal one, at least under certain conditions. I test this hypothesis and find that the predicted relationship holds when housing prices are measured by rents and the general price level is instrumented to account for measurement error. When housing prices are measured by housing values, however, the wage-price elasticity is significantly less than one, even using instrumental variables. Rents reflect the price paid for housing per unit of time and are arguably the superior measure. Thus, findings in this essay provide support for the full compensation hypothesis. These findings also have important implications for researchers estimating the implicit prices of amenities or ranking the quality of life across areas.

Flexible collective bargaining agreements: Still a moderating effect on works council behaviour?

We analyse the interaction between different labour market institutions in Germany, namely, industry‐level bargaining and firm‐level codetermination by works councils. In particular, we are interested in the moderating effect of flexibility measures on the link between the existence works councils and collective agreements on wages and productivity. In presence of institutional changes, the question is whether works councils in covered plants still generate rather than redistribute rents, given recent decentralisation processes in the German system of industrial relations. We augment a theoretical model to provide hypotheses, which are then tested using empirical analysis of representative German plant level data. We find that the existence of flexibility provisions in collective bargaining agreements does not alter the effect of works council on firms' wages. We find, however, that with flexibility provisions works council presence is associated with higher productivity levels than without such provisions. These findings, however, depend on the level of collective bargaining: they can only be observed in plants covered by industry‐level contracts, but do not hold in plants covered by firm‐level contracts.     

Measuring regional inequality: to weight or not to weight?

Measuring regional inequality: to weight or not to weight? Spatial Economic Analysis. When estimating regional inequality, many economists use inequality indices weighted by regions’ proportion of the national population. Although this approach is widespread, its adequacy has not received attention in the regional science literature. This paper proves that such an approach is conceptually inconsistent, yielding an estimate of interpersonal inequality among the whole population of the country rather than an estimate of regional inequality. Nevertheless, as a measure of interpersonal inequality, such an estimate is very rough (even misleading) and does not always have an intuitive interpretation. Moreover, population-weighted inequality indices do not meet the requirements for an adequate measure of inequality.     

In what sense ‘regional development?’: entrepreneurship,underdevelopment and strong tradition in the periphery

This paper explores whether entrepreneurship can help less successful regions to improve their regional economic situation, without all the benefits that entrepreneurship brings when being ‘stripped out’ to more successful regions. The paper uses the idea that peripheral regions possess qualities of tradition and underdevelopment, and that these help to anchor new firms into these regions, resistant to their concentration in core regions. The paper explores whether particular entrepreneurial events can be regarded as ‘densifying’ the regional entrepreneurial environment, thereby making a positive contribution to its economic development. The paper explores the role of these negative anchors to the entrepreneurial events and the densification process by following a sequence of high-technology spin-out firms in the North East of England. Using a realist methodology attempting to interview all the firms within the sequence which could be found, the paper discovers that quite positive advantages exist within these negative qualities.The paper then considers whether these processes, such as plant closure, might drive entrepreneurship in all regions.     

GARCH models without positivity constraints: Exponential or log GARCH?

This paper provides a probabilistic and statistical comparison of the log-GARCH and EGARCH models, which both rely on multiplicative volatility dynamics without positivity constraints. We compare the main probabilistic properties (strict stationarity, existence of moments, tails) of the EGARCH model, which are already known, with those of an asymmetric version of the log-GARCH. The quasi-maximum likelihood estimation of the log-GARCH parameters is shown to be strongly consistent and asymptotically normal. Similar estimation results are only available for the EGARCH (1,1) model, and under much stronger assumptions. The comparison is pursued via simulation experiments and estimation on real data.     

Are Mainstream and Heterodox Economists Different? An Empirical Analysis

We explore the differences between mainstream and heterodox economists based on the responses to a questionnaire from a representative sample of Italian economists. Using different definitions for mainstream and heterodox economics, we compare the individual and academic characteristics of the economists belonging to these groups. We measure the within and between disagreement for each group and we test whether belonging to one or the other group predicts differences in economists' opinions on economic policy. Results show that: 1) mainstream and heterodox economists differ as to individual and academic characteristics and political views; 2) the disagreement within heterodox economics is lower than within mainstream economics; 3) some of commonly used ways of grouping heterodox and mainstream schools of thought have little explicative power in relation to individual opinions; 4) on critical economic policies, the opinions of heterodox and mainstream economists are significantly different even after controlling for a number of individual characteristics, including political opinions.     

To pool or not to pool: What is a good strategy for parameter estimation and forecasting in panel regressions?

This paper considers estimating the slope parameters and forecasting in potentially heterogeneous panel data regressions with a long time dimension. We propose a novel optimal pooling averaging estimator that makes an explicit trade‐off between efficiency gains from pooling and bias due to heterogeneity. By theoretically and numerically comparing various estimators, we find that a uniformly best estimator does not exist and that our new estimator is superior in nonextreme cases and robust in extreme cases. Our results provide practical guidance for the best estimator and forecast depending on features of data and models. We apply our method to examine the determinants of sovereign credit default swap spreads and forecast future spreads.
