More than energy transformations: a historical transition from organic to industrialized farm systems in a Mediterranean village (Les Oluges,Catalonia, 1860–1959–1999)

The analysis of energy efficiency of agroecosystems from a sociometabolic perspective is a useful way to assess the sustainability of farm systems. In this paper we examine the transition of a Mediterranean agroecosystem from an organic farm system in the mid nineteenth century to an industrialized one at the end of the twentieth century by means of the technologies and ideology of the Green Revolution. Given that many of the world’s agricultural systems have experienced, or are currently experiencing this transformation, our results are relevant for building more sustainable agricultural systems in future. Our results highlight the relevance of livestock density, and the flows of biomass reused and unharvested biomass as key elements affecting the sustainability of the agroecosystem not only from a socioeconomic perspective, but also from an agroecological point of view. Additionally, from a biocultural perspective our investigation sustains the relevance of the study of traditional farm systems for the development of a sustainable agriculture.     

Entrepreneurial orientation in family firms: the moderating role of technological intensity and performance

This paper examines how socio-emotional factors can influence family firms’ commitment to entrepreneurially- oriented activities, and how their level of commitment is moderated by the technological intensity of the sector and firm performance. We find that, while family firms are less entrepreneurially-oriented than non-family firms, this gap closes with increasing technological intensity of the sector. We find no evidence, however, to suggest any change in entrepreneurial orientation in family firms resulting from a drop in firm performance.     

Managerial compensation

We review the existing literature on managerial compensation, with particular reference to the two contrasting views about its main driver. On the one hand, managerial compensation is seen to be the result of a market-based mechanism which ensures that managers have adequate incentives to maximize shareholder value. On the other hand, it is regarded to be a means whereby self-serving executives skim corporate profits and expropriate shareholders. We find that most of the existing literature supports the latter view as executives tend to benefit from windfall earnings and are able to extract rents in the presence of weak corporate governance.     

The Performance of the European Market for Corporate Control: Evidence from the Fifth Takeover Wave

This paper presents an in‐depth analysis of the performance of large, medium‐sized, and small corporate takeovers involving Continental European and UK firms during the fifth takeover wave. We find that takeovers are expected to create takeover synergies as their announcements trigger statistically significant abnormal returns of 9.13% for the target and of 0.53% for bidding firms. The characteristics of the target and bidding firms and of the bid itself are able to explain a significant part of these returns: (i) deal hostility increases the target's but decreases bidder's returns; (ii) the private status of the target is associated with higher bidder's returns; and (iii) an equity payment leads to a decrease in both bidder's and target's returns. The takeover wealth effect is however not limited to the bid announcement day but is also visible prior and subsequent to the bid. The analysis of pre‐announcement returns reveals that hostile takeovers are largely anticipated and associated with a significant increase in the bidder's and target's share prices. Bidders that accumulate a toehold stake in the target experience higher post‐announcement returns. A comparison of the UK and Continental European M&A markets reveals that: (i) the takeover returns of UK targets substantially exceed those of Continental European firms. (ii) The presence of a large shareholder in the bidding firm has a significantly positive effect on takeover returns in the UK and a negative one in Continental Europe. (iii) Weak investor protection and low disclosure in Continental Europe allow bidding firms to adopt takeover strategies enabling them to act opportunistically towards the target's incumbent shareholders.     

Consumption risk, technology adoption and poverty traps: Evidence from Ethiopia

Much has been written on the determinants of technology adoption in agriculture, with issues such as input availability, knowledge and education, risk preferences, profitability, and credit constraints receiving much attention. This paper focuses on a factor that has been less well documented: the differential ability of households to take on risky production technologies for fear of the welfare consequences if shocks result in poor harvests. Building on an explicit model, this is explored in panel data from Ethiopia. Historical rainfall distributions are used to identify consumption risk. Controlling for unobserved household and time-varying village characteristics, it emerges that not just ex ante credit constraints, but also the possibly low consumption outcomes when harvests fail, discourage the application of fertilizer. The lack of insurance or alternative means of keeping consumption smooth leaves some trapped in low return, lower risk agriculture, one of the mechanisms through which poverty perpetuates itself in agrarian settings.     

Strategic response to GMOs by GM-free countries

This article examines the dilemma of a large exporting countryof an agricultural product that has to determine whether ornot to approve genetically modified (GM) products with or withouta labelling regime. We derive two main results. First, the approvaldecision on GM products is specific to the labelling regime:approval of GM products is optimal under a labelling regime,whereas non-approval is optimal in the absence of a mandatorylabelling requirement. Second, the inability to protect theinnovator's rent through IPR enforcement can prevent the approvalof GM products.     

The monetary appreciation of paintings: from realism to Magritte

This study investigates how investments in paintings comparewith those in stocks in terms of risk–return trade-offusing Sharpe and Treynor ratios and Markowitz efficient frontiers.A large database was analysed consisting of more than 10,500auction prices of Belgian paintings over the period 1970–97.These paintings are the auctioned oeuvre of 71 internationallyrecognised painters representing the main artistic schools (fromsocial realism to surrealism) over the period 1850–1950.Hedonic art returns are corrected for auction location and auctionhouse, artistic school, painters' reputation, medium, signatureand painting size. Surrealism and luminism have been the mostpopular currents of art (in monetary terms), while expressionismand symbolism have gained (financial) esteem. This study concludesthat art investments underperform equity market investmentsowing to the high risk of investing in art and its high transactioncosts, resale rights and insurance premia. In addition, theMarkowitz efficient frontier shows limited diversification potentialfor art.     

Corporate Restructuring and Bondholder Wealth

This paper provides an overview of existing research on how corporate restructuring affects bondholder wealth. Restructuring is defined as any transaction which affects the firm's riskiness by changing its underlying capital structure. Thus, it reaches well beyond asset restructuring and includes transactions such as leveraged buyouts, security issues and exchanges, and the issuance of stock options. We identify significant gaps in the literature, emphasize the potential differences in bond performance between market‐ and stakeholder‐oriented corporate governance systems, and provide valuable insights into methodological advances. We find that many issues remain as the empirical evidence is often inconclusive and focuses almost exclusively on the US. Research on other countries remains constrained by the lesser development of their bond markets, but is equally imperative because the position and bargaining power of creditors vis‐à‐vis the firm differ substantially across countries and governance regimes.     

Employee isolation and support for change in the public sector: a study of the internal audit profession

ABSTRACT

We investigate the preferences of public sector internal auditors for changes in their work practices. Informed by the literature, we posit that feelings of trust in the workplace and/or frustrations arising from perceived organizational ‘isolation’—a dimension of work alienation—motivate support and acceptance of change. We also argue that professional bodies directly and indirectly influence these relationships. These conjectures are tested using structural equation modelling and a survey of Canadian public sector internal auditors. The findings provide valuable insights into the process of adaptation and transformation in public sector settings across countries, jurisdictions, and accountability functions.
