An investigation into international assignment directions of R&D MNE employees: evidence from Greece

In this study, we explore the effects of the roles of research and development (R&D) laboratories, roles of subsidiaries and level of technological intensity of the sector in which multinational enterprise (MNE) subsidiaries operate on international assignment directions of R&D employees. International assignments are an underinvestigated issue in the international human resource management literature despite its significant research and managerial importance. In particular, to the best of our knowledge, no prior research on international assignments of R&D employees has been undertaken and so the current study aims at filling this void in the literature. Based on a large quantitative research on MNE subsidiaries operating in Greece, the findings suggest that variables of the aforementioned categories of factors influence different international assignment directions, with roles of the R&D subsidiary exerting the most crucial effect. Researchers may examine the unexplored issue of R&D employee international assignments to a larger extent, while MNE management can particularly take into account the micro (laboratory) context of R&D international assignees when developing effective international human resource management programmes.     

Inflation,Monetary Policy and Reserve Requirement Ratio Adjustments in China

This study examines the relationship between inflation rate and reserve requirement ratio in China. Our findings show that there is a long-term relationship between reserve requirement ratio and inflation rate. In the short-run, the central bank adjusts the reserve requirement ratio upwards faster than they adjust them downwards. The asymmetric adjustment reflects the fact the Chinese economy was overheating over the past few years as a result of the stimulus package implemented after the onset of the global financial crisis and inflation was threatening the stability of the society.     

Stock market volatility and equity returns: Evidence from a two-state Markov-switching model with regressors

This paper proposes a two-state Markov-switching model for stock market returns in which the state-dependent expected returns, their variance and associated regime-switching dynamics are allowed to respond to market information. More specifically, we apply this model to examine the explanatory and predictive power of price range and trading volume for return volatility. Our findings indicate that a negative relation between equity market returns and volatility prevails even after having controlled for the time-varying determinants of conditional volatility within each regime. We also find an asymmetry in the effect of price range on intra- and inter-regime return volatility. While price range has a stronger effect in the high volatility state, it appears to significantly affect only the transition probabilities when the stock market is in the low volatility state but not in the high volatility state. Finally, we provide evidence consistent with the ‘rebound’ model of asset returns proposed by Samuelson (1991), suggesting that long-horizon investors are expected to invest more in risky assets than short-horizon investors.     

ON THE SOURCES OF UNCERTAINTY IN EXCHANGE RATE PREDICTABILITY

In a unified framework, we examine four sources of uncertainty in exchange rate forecasting models: (i) random variations in the data, (ii) estimation uncertainty, (iii) uncertainty about the degree of time variation in coefficients, and (iv) uncertainty regarding the choice of the predictor. We find that models that embed a high degree of coefficient variability yield forecast improvements at horizons beyond one month. At the one‐month horizon, and apart from the standard variance implied by unpredictable fluctuations in the data, the second and third sources of uncertainty listed above are key obstructions to predictive ability. The uncertainty regarding the choice of the predictors is negligible.     

Escapism FDI from developed economies: The role of regulatory context and corporate taxation

In this paper, we extend the conceptualisation of escapism Foreign Direct Investment (FDI) holding for emerging economies to developed economies that face specific institutional failures, such as weak or incomplete regulations, along with high taxation. We combine this literature with the recent development of Dunning’s eclectic paradigm, which includes institutional aspects regarding location factors. We argue that in developed economies with problematic regulations and high taxation, sound institutions and lower tax rates abroad are extremely significant for domestic firms’ internationalisation. A central result regards the moderating effect of host regulatory quality on taxation, which highlights the crucial role of institutions for firms originating in developed economies that lack sound institutions. Additionally, the results challenge the available theorising and evidence on the moderating role of institutions in the prior experience of a firm at a location. We instead provide evidence that once firms establish a subsidiary abroad, they acquire substantial knowledge about the host institutional environment, which translates into an Ot advantage, providing an additional motive for further expansion. This work uses a unique database of the total population of Greek MNEs – released for the first time – for an extended time period, 2001–2010. The results could be generalised to similar developed economies facing analogous regulatory failures and high taxation, such as the southern European Union countries, as well as even for northern European Union countries, such as Germany, according to Bundesbank’s report.     

Individual investors and local bias in the UK, 1870–1935

This article examines the long‐run evolution of local bias by UK investors between the 1870s and the 1930s. It uses a large sample of nearly 30,000 shareholders based on 197 sets of share records, a large and representative database of the investor population across sectors and time. It investigates the structure and the evolution of local investment preference between shareholders and the companies in which they invested, as measured by the distance between where they lived and corporate headquarters. The study offers evidence of strong initial local investment preference, which declined over time for non‐Londoners, but remained strong for Londoners until the 1930s. Local investment preference of security holders was related to the size of the board of directors and, for wealthy investors, was related to the age of the firm. For large firms, local networks between investors and directors appear stronger when director shareholdings and voting rights were important. This study supports the analytical hypothesis of local informal trust networks between investors and directors as a means to overcome informational asymmetries and weak legal protection, and provides evidence that local preference was a means to curb insider opportunism and private benefits of control.     

REVISITING THE REAL WAGES–UNEMPLOYMENT RELATIONSHIP. NEW RESULTS FROM NON-LINEAR MODELS

We examine the long-run real wages–unemployment relationship for five OECD countries over the period 1960:1–2001:4. Given the theoretical possibility of non-linear equilibrium due to downward real wage rigidity we employ econometric tests that allow for the presence of non-linearities in the long-run equilibrium. We adopt the notion of 'hidden co-integration' suggested by Granger and Yoon . This methodology has several advantages with respect to other non-linear models. We find statistical evidence that, in general, there is a long-run positive relation between real wages and unemployment only when both are affected by positive shocks. We also find a negative relationship between unemployment and productivity. The empirical analysis is complemented with the estimation of error correction models for all countries.     

Composition versus decomposition in two-stage network DEA: a reverse approach

A two-stage production process assumes that the first stage transforms external inputs to a number of intermediate measures, which then are used as inputs to the second stage that produces the final outputs. The fundamental approaches to two-stage network data envelopment analysis are the multiplicative and the additive efficiency-decomposition approaches. Both they assume a series relationship between the two stages but they differ in the definition of the overall system efficiency as well as in the way they conceptualize the decomposition of the overall efficiency to the efficiencies of the individual stages. In this paper, we first show that the efficiency estimates obtained by the additive decomposition method are biased, by unduly favouring one stage against the other, while those obtained by the multiplicative method are not unique. Then, we present a novel approach to estimate unique and unbiased efficiency scores for the individual stages, which are then composed to obtain the efficiency of the overall system, by selecting the aggregation method a posteriori. Within the particularity of two-stage processes emerging from the conflicting role of the intermediate measures, we develop an envelopment model to locate the efficient frontier whose derivation from our primal multiplier efficiency assessment model is effectively justified. The results derived from our approach are compared with those obtained by the aforementioned basic methods on experimental data as well as on test data drawn from the literature. Similarities and dissimilarities in the results are rigorously justified.     

Productivity, convergence and policy: a study of OECD countries and industries

This paper analyses trends in labour productivity and its underlying determinants in a panel of OECD countries from 1979 to 2002. Data Envelopment Analysis (DEA) is used to estimate a Malmquist measure of multifactor productivity (MFP) change. We decompose the growth in labour productivity into (i) net technological change (ii) input biased technical change (IBTC) (iii) efficiency change and (iv) capital accumulation. We analyse the effect of each of these factors in the transition towards the equilibrium growth paths of both labour productivity and per capita GDP for the OECD countries, controlling for the effects of different policies and institutions. The results indicate that on average gaps in productivity or income levels are narrowing down although there is no evidence to suggest that the entire OECD area comprises a single convergence “club”. Using kernel estimation methods we find that that labour productivity and per capita GDP are settling toward a twin peak (bimodal) distribution. Panel unit root tests over an extended (1960–2001) period provide general support for the convergence hypothesis. Analysis of the contributions of productivity growth within industries and sectoral composition changes show that aggregate productivity change is predominantly driven by ‘net’ within sector effects with very little contribution emerging from sectoral shifts (the ‘in-between’ static or dynamic effects resulting from higher or above average productivity industries gaining employment shares or low productivity industries losing shares).     

Insider trading and future stock returns in firms with concentrated ownership levels

We investigate the relationship between insider trading and stock returns in firms with concentrated ownership. To this end, we employ data from East Asian countries which span the period January 2003 to May 2012. Consistent with the previous literature, we find a significantly negative relation between the selling activity of insiders and stock returns. However, contrary to studies which focus on highly developed markets, we find that the buying activity of insiders is also inversely related to future stock returns. Our analysis shows that top directors with higher ownership levels drive this result, suggesting that the trading activity of insiders is not always associated with profit-making motives and can be explained by their level of ownership. Furthermore, we demonstrate that a trading strategy which focuses solely on purchases made by top directors with high ownership levels yields negative returns. The paper has important implications for outside investors who mimic the trading activity of insiders with the aim to realise profits.
