Strategic and Tactical Roles of Enhanced Commodity Indices

This article formally compares two traditional long‐only commodity indices, Standard & Poor's Goldman Sachs Commodity Index (S&P‐GSCI) and Dow Jones‐UBS Commodity Index (DJ‐UBSCI), with their enhanced versions that exploit signals based on contract maturity, momentum, and term structure. The enhanced indices are found to be useful for tactical asset allocation. With alphas ranging from 2.77% to 5.49% per annum, the maturity‐enhanced indices offer the best abnormal performance after accounting for liquidity risk. Momentum and term structure enhancements also earn a positive, albeit smaller, alpha of 2.10% per annum on average. All the enhanced indices are found to have comparable effectiveness for risk diversification and inflation hedging as their traditional counterparts, making them useful for strategic asset allocation.     

Are Full Employment and Social Cohesion Possible Under Financialization?

Unemployment and unequal income distribution were singled out by J.M. Keynes, in the General Theory, as major faults of capitalist economies. This paper argues that there is a negative relationship between financialization and unemployment. In particular, we develop a simple Post Keyneian/Kaleckian model and explore distribution as well as institutional channels through which financialization might have negatively affected the employment performance of capitalist economies, undermining the social cohesion and egalitarian development. Furthermore, we argue that in the face of financialization full employment is likely to be attainable under the institutionalization of an Employer of Last Resort (hereafter ELR) policy strategy.     

Accruals and the performance of stock returns following external financing activities

This paper investigates the relation of the external financing anomaly with the accrual anomaly, by focusing separately on working capital accruals and long-term accruals. We find that external financing and accrual hedge portfolios not only generate superior returns, but they also constitute statistical arbitrage opportunities. Portfolio-level analysis and firm-level cross-sectional regressions show that the ability of external financing measures in predicting future returns remains strong, after controlling for working capital accruals. However, this ability is substantially reduced after controlling for long-term accruals. Our results appear to be consistent with investors’ failure to recognise agency-related overinvestment and/or opportunistic earnings management.     

Tactical allocation in commodity futures markets: Combining momentum and term structure signals

This paper examines the combined role of momentum and term structure signals for the design of profitable trading strategies in commodity futures markets. With significant annualized alphas of 10.14% and 12.66%, respectively, the momentum and term structure strategies appear profitable when implemented individually. With an abnormal return of 21.02%, our double-sort strategy that exploits both momentum and term structure signals clearly outperforms the single-sort strategies. This double-sort strategy can additionally be utilized as a portfolio diversification tool. The abnormal performance of the combined portfolios cannot be explained by a lack of liquidity, data mining or transaction costs.     

The financial fragility and the crisis of the Greek government sector

The purpose of this paper is to develop Minskyan financial fragility indices for the government sector and to examine the financial structure of the Greek government before and after the onset of the sovereign debt crisis in 2009. We provide empirical evidence that clearly shows the growing financial fragility of the Greek public sector in the 2000s. We also assess the effectiveness of the implemented bailout adjustment programmes in Greece and claim that the conducted austerity measures and fiscal consolidation have not significantly improved the financial posture of the Greek government sector. We argue that the implementation of fiscal and wage austerity in an economy that lacks structural competitiveness produces prolonged recession and unemployment with adverse feedback effects on the financial fragility of the government.     

Entrepreneurship in post‐conflict transition1

We examine new self‐employment entry and its viability in Bosnia and Herzegovina, using a rich household survey for the years 2001–2004. We find that wealthier households are more likely to engage in viable self‐employment and create employment suggesting an important role for financing constraints. Specifically, although having an existing bank relationship is not significantly related to the entry decision, it is positively related to the survival for new entrepreneurs and their employment creation. We also find a non‐linear relationship between remittances and entry in that individuals not receiving remittances are more likely to enter self‐employment; but, if they do receive them, the likelihood of starting a business increases in the fraction of wealth received from domestic remittances. Finally, people working in the informal sector are more likely to become viable entrepreneurs, particularly those provided with loans from micro‐credit organizations. These findings support the perception of the informal sector as an incubator for formal self‐employment in the early years of transition.     

Political cycles in Greece’s municipal employment

We consider the politically motivated fluctuations in Greece’s municipal employment, constructing a data-set from primary data and focusing on the composition of municipal employment in terms of employment relationship forms. Our analysis produces strong evidence of pre-electoral manipulation through increases in the number of contract employees. Considering a number of control variables and robustness checks does not affect the key results. Such variables include whether mayors run for reelection, incumbents’ political alignment with central government, partisan shifts, general elections, mayors’ turnover rate, and timing patterns. Our evidence provides insights into Greece’s political economy in the run-up to the current economic crisis.     

The Relevance of the Monetary Model for the Euro / USD Exchange Rate Determination: a Long Run Perspective

This study tries to fill a vacuum in the literature on the relevance of economic fundamentals for the Euro / USD exchange rate determination. We adopt the Monetary Model for the Exchange Rate Determination as our testing vehicle and investigate the relevance of various versions of this model over a long time horizon, spanning the period from the inception of Euro till the present time. We rely on cointegration analysis to conduct our empirical research and in accordance to the relevant literature we fail to accept most of the variants of this model. However, we get encouraging results from an expanded version of the Monetary Model where demand and productivity factors appear in the set of the exchange rate determinants.     

Firm Growth and FDI: Are Multinationals Stimulating Local Industrial Development?

The aim of this paper is to improve our understanding of the empirical determinants of firm growth by extending the literature to include a new group of variables related to foreign direct investment (FDI), namely the degree of foreign ownership and technology spillovers. Based on recent developments in the field, our analysis also encompasses the role of sunk costs and financial constraints, while quantile regression techniques are adopted as more suitable to the data available (2,640 manufacturing firms operating in Greece in the 1992–1997 period). Our findings highlight the role of FDI in increasing firm growth with varying intensity depending on industry groups and regression quantiles, and vindicate the use of new variables.
