Existence of solutions in continuous-time optimal growth models

This paper studies the existence of solutions in continuous time optimization problems. It provides a theorem whose conditions can be easily checked in most models of the optimal growth theory, including those with increasing returns and multi-sector economies.      

Contribution to social exchange in public organizations: examining how support,trust, satisfaction,commitment and work outcomes are related

The intent of the research was to examine the relationships between support, trust, satisfaction, commitment and work outcomes. The framework of social exchange theory was used as a guide. The research described in this study replicates in the public sector (N = 704) and previous findings obtained in a study conducted in the private sector. Consistent with the study in private sector, support is related to intention to leave and helping behavior to trust and satisfaction. Results are discussed.     

Which Dimensions of Social Responsibility Concern Financial Investors?

Social and environmental ratings provided by social rating agencies are multidimensional. The first goal of our paper is to identify a small number of independent and relevant socially responsible (SR) dimensions reflecting a firms’ coherent posture toward social issues. We put forward that these dimensions are not exactly the same as the ESG ones (Environment, Social, and Governance). Using the six sub-ratings provided by the Vigeo rating agency, we perform a principal component analysis and we highlight three main independent SR dimensions related to (1) business stakeholders (employees, customers, and suppliers), (2) societal stakeholders (environment and society), and (3) financial stakeholders (stockholders and debt holders). The second objective of our paper is to explore the link between stock returns and these three SR dimensions. Our most notable finding is that for each SR dimension, investors ask for an additional risk premium when they accept to hold non-socially responsible stocks. The cost of equity is thus lower for SR firms. The average premium over the period 2003–2010 is larger for the components “business stakeholders” and “financial stakeholders” than for the component “societal stakeholders.” The premium for this last component has only existed since the end of 2008. Since that time, environment and community involvement have become important risk factors strongly considered by investors. For the three dimensions, investors notably penalize large non-social firms and reward small social firms.     

Large shareholders and corporate governance

The paper looks at the voluntary provision of governance to outside shareholders by an entrepreneur who takes his firm public but remains a large shareholder after the IPO. We find that the entrepreneur always puts in place an independent board which acts in the interests of the outside shareholders, but may put in place a friendly remuneration committee that ensures that CEO pay is structured to suit the entrepreneur in the cases where the retained equity stake is sufficiently large. When comparing this provision of governance to the provision preferred by a welfare maximizing regulator, we find that both voluntary overprovision and underprovision of governance can happen. Overprovision of governance happens in the cases where the entrepreneur commits to independence at the level of the remuneration committee when the regulator prefer a friendly remuneration committee. Underprovision of governance takes the form of establishing a friendly remuneration committee (with an independent board), when the regulator would prefer an independent remuneration committee (with a friendly board). We discuss the empirical predictions of the model.     

Interval bidding in a distribution elicitation format

Interval bidding allows people to report a range of values for a non-market good. Herein, we allow people to choose their distribution over this range endogenously. We consider a multiplicative error model explaining the willingness to pay (WTP) which is estimated using a feasible generalized least squares estimator. We apply our framework to a representative sample of the French population who were asked about the valuation of a bear conservation programme. We find that most participants prefer stating their WTP as a range rather than a point, but the shape of the distribution greatly varies across people. Our results support the use of the interval bidding with endogenous distribution approach in valuation studies.     

What Future for the EU in the Global Trading System?

The recent phase of globalisation could be characterised as “wider”, whereas the next phase to come will be “deeper”. This new phase is likely to prove bumpier than the previous one, as the issues now at stake will have more to do with values or ethics, the interpenetration of which will be both economically necessary and politically difficult. In the medium term, the growth of the European economies will become more dependent on external trade, and thus these policy challenges will need to be addressed.     

Collapse Through Collectivisation

International banks, stimulated by a government weakening of property rights, have over-lent to uncredit-worthy borrowers and precipitated a crisis in the international financial system, according to Professor Pascal Salin of the Université de Paris-Dauphine. He argues that the return of responsibility can be accomplished only through o reliance on private - not government -capital administered by bankers who bear the risk of their own actions, and sound monetary policies to restore the value of savings through the reduction of inflation.     

The “Treasury View”: An (un-)expected return?

Abstract

By examining the rhetorical use of an old piece of economic theory by some contemporary economists, this paper intends to report on “how today's economists conduct a public policy debate”. This paper is neither a scholarly history of the interwar debate nor a sophisticated critique of current economic policy. It is an attempt to link the policy and theoretical arguments of two similar debates separated by nearly 80 years. The second part of the paper demonstrates that the (un-)expected return of the Treasury View is a case study illustrating two very different modelling strategies.     

On the Practical Application of the Real Options Theory

This article aims to present and explain the potential of the real options theory. This theory can help solve many corporate problems in the field of investment strategies. It incorporates a wide range of internal and external factors that are playing a potential role in strategy outcome. The real options tool has already been applied in many industries and many divisions of their business. The main advantage of this methodology is that management is forced to develop a more structured thinking pad due to the fact that real options is based on a clear and accurate procedure. © 2001 John Wiley & Sons, Inc.
