Bucking the Trend: The Informativeness of Analyst Contrarian Recommendations

This paper examines price reactions to analysts’ recommendations issued in the opposite direction of recent stock price movements. We find that upgrade and downgrade contrarian recommendations induce larger market reactions than noncontrarian recommendations, consistent with the view that they are more informative. These results are strongest in the period before Regulation Fair Disclosure, consistent with the view that private information was likely curbed after its implementation. Contrarian downgrades are more likely to be issued by all‐star analysts, but less likely by experienced and busy analysts suggesting that contrarian recommendations are subject to career concerns.     

Assessing the impact of liberalisation policies on the Greek labour market: an insider–experts' view from the perspective of the varieties of liberalisation

During the recent Great Recession (2008–2018), Greece has become the prototype example of the implementation of austerity policies in Europe. Contrary to public discourse, these austerity policies were complemented by substantial labour market reforms that promoted employment and wage flexibility. This article aims to present a theory-driven understanding of the implementation and the effects of these reforms. For this purpose, we employ a qualitative study consisting of semi-structured interviews with 50 labour market experts—government officials and labour lawyers, academics, labour union representatives and employer association representatives. Using Thelen's framework on the Varieties of Liberalization, we conclude that, contrary to the initial aims of the reforms, Greece followed a trajectory of direct deregulation, reducing considerably the level of both coordination between employers and workers, and coverage of employment protection. The interviews show that the dismantling of collective bargaining system was the most decisive move in this path.

Does Firing a CEO Pay Off?

We examine whether involuntary chief executive officer (CEO) replacements pay off by improving firm prospects. We find CEO successors’ acquisition investments to be associated with significantly higher shareholder gains relative to their predecessors and the average CEO. This improvement in postturnover acquisition performance appears to be a function of board independence, hedge fund ownership, and the new CEO's relative experience. CEO successors also create sizable shareholder value by reversing prior investments through asset disposals and discontinuing operations and by employing more efficient investment strategies. Our evidence suggests that firing a CEO pays off.     

Coordinating climate and trade policies: Pareto efficiency and the role of border tax adjustments

This paper explores the role of trade instruments in globally efficient climate policies, focusing on whether or not some form of border tax adjustment (BTA) is warranted when carbon prices differ internationally. The analysis shows that, while there is no case for BTA when all instruments can be freely deployed, Pareto-efficiency does require a form of BTA when carbon taxes in some countries are constrained: its purpose then is to partly counteract the impact on emissions of inappropriate carbon pricing there, or, equivalently, to undo the trade distortions such pricing creates. The required form of BTA is generally complex, but a special case is identified in which it optimally has the simple structure envisaged in practical policy discussions. It is also shown that the efficiency case for BTA depends critically on whether climate policies are pursued by carbon taxation or by cap-and-trade.     

Investigation of current perspectives for NHS Wales sustainable development through procurement policies

Public sector procurement has to operate under the pressure of policies and strict budgets. This paper examines the current perspectives of the NHS Wales Shared Services Partnership (NWSSP) on sustainable procurement policies. In particular, it investigates the adoption levels of the sustainable procurement policies of buyers (NHS Wales), examines the level of engagement of small- and medium-sized enterprises (SMEs) with NHS Wales, and explores the support for the existing sustainable procurement function through order processing analysis of catalogue coverage.     

An empirical assessment of proposed solutions for resolving scale problems in value relevance accounting research

We implement the most common empirical specifications, with different approaches to control for scale problems, used in studies on the value relevance of accounting information. We study whether the results offered by these specifications are consistent with the residual income valuation model and with the Burgstahler and Dichev option-style valuation framework. Undeflated and per-share specifications offer results that are more in line with both benchmarks. Other deflated specifications and approaches deviate, to different extents, from the expectations of both frameworks. We interpret these deviations as signs of misspecification.     

Exploring the determinants of the OSS market potential: The case of the Apache web server

A theoretical framework is proposed for the better understanding of the OSS global diffusion. Following a case study approach, the Apache web server's market potential is estimated, forecasted and examined in terms of the socio-economic factors determining its diffusion, across different economic environments in developed versus developing countries. Market saturation is explored under the prism of three theoretical perspectives: the institutional, the endogenous and the exogenous growth theories. Findings suggest that Apache market saturation levels depend on both endogenous and exogenous to a country factors and that institutional quality plays an important role to the market potential. Implications for theory and public policy are discussed.     

Fiscal and Monetary Policy Interaction in a Simple Accelerator Model

In this paper, a simple Keynesian and discrete time multiplier ?C accelerator model is developed, which results after the inclusion of the money market and a balanced government budget constraint in Samuelson??s (1939) business cycle model. The resulted model is proved to be less stable and the evolution of income around its equilibrium is more likely to exhibit a sinusoidal way of movement. The magnitude of the main tools of fiscal and monetary policy is assumed to be determined solely by the government and the Central Bank respectively, so that income??s constant amplitude around its intertemporal equilibrium value is minimized.     

Saving rates and portfolio choice with subsistence consumption

We analytically show that a common across rich/poor individuals Stone-Geary utility function with subsistence consumption in the context of a simple two-asset portfolio-choice model is capable of qualitatively and quantitatively explaining: (i) the higher saving rates of the rich, (ii) the higher fraction of personal wealth held in risky assets by the rich, and (iii) the higher volatility of consumption of the wealthier. On the contrary, time-variant “keeping-up-with-the-Joneses” weighted average consumption which plays the role of moving benchmark subsistence consumption gives the same portfolio composition and saving rates across the rich and the poor, failing to reconcile the model with what micro data say.
