The Marshallian Market and the Walrasian Economy. Two Incompatible Bedfellows

The aim of this paper is to question a view which is usually taken for granted, namely that the Marshallian partial equilibrium and Walrasian general equilibrium analysis stand in a relationship of continuity. It will be claimed that the contrary is true: the generalisation of the Marshallian market does not lead to a Walrasian economy or, conversely, the Walrasian economy is not composed of Marshallian markets. To bring this point home, the basic methodological choices underpinning the analysis of the Marshallian market and of the Walrasian economy will be compared. The issue of why no full-fledged Marshallian representation of the economy has arisen which might stand as an alternative to the Walrasian account will also be investigated and a series of reasons for this lack of generalisation of the Marshallian market will be considered. Finally, it will be claimed that if the Marshallian economy concept has no explicit existence, it has nonetheless an implicit one. It forms the background against which a series of reasoning about the working of the economy as a whole, which cannot fit the Walrasian economy framework, are developed. No less prestigious names than those of Keynes, Hicks, Patinkin, Friedman, Clower and Leijonhufvud will be adduced as witnesses.

Making Banks in Europe More Responsible

The financial crisis is still hitting families and businesses across Europe hard.We can't let such a crisis happen again and we can't allow the actions of a few in the financial world to jeopardise the rest of society. The IMF estimates European banks made losses close     

Estimating the social cost of pesticide use: An assessment from acute poisoning in Brazil

The intensive use of pesticides in countries like Brazil has ignored structural and institutional shortfalls, such as the lack of workforce training for the new, difficult to implement technologies, and the institutional vulnerability of the environmental protection, health, and safety sectors. As a result we have “invisible” or social, environmental and health costs which end up being socialised with the farmer, in general, having no incentives to recognise and internalise them. This study is intended to review and develop this problem in the light of the Brazilian reality. To this end, we make use of an empirical exercise to illustrate estimation of the social cost associated with acute poisoning by pesticide using the PREVS/IBGE data (Harvest Forecast Research) in the state of Paraná, Brazil. The results suggest that, for maize, the costs of acute poisoning could represent 64% of the benefits of using herbicides and insecticides, and, in the best of hypotheses, when some risk factors are eliminated, they may reach 8% of the benefits of the use of these products. Similarly, when we examine future scenarios for five and ten years, we find less encouraging results, as in ten years the costs of acute poisoning could reach around 85% of the benefit of using insecticides and herbicides for maize. However, there is the encouraging news that, if preventive measures were taken during this time, the gains would be considerable, about 6.5 times greater. We conclude that an assessment of the real benefits involved with pesticides in Brazil is required, principally in regard to the smallholder, where farmers need more training in the use — or even the elimination — of these hazardous substances. There are sustainable technological options available which are economically efficient, especially if we consider the social, environmental and health costs. In this context it is worth highlighting the role of regulatory measures as a mechanism which can reorient generation of negative external costs through the reduction of current incentives in the socialisation of private costs.     

Fiscal Policy when Individuals Differ with Regard to Altruism and Labor Supply

This paper studies the incidence of tax-transfer policy in a growth model wherein individuals differ according to their level of intergenerational altruism and have an endogenous labor supply. The main result is that public debt is neutral at the macro level but redistributes resources from nonaltruists to altruists. Capital income taxation can hurt the nonaltruists who do not have any wealth more than it hurts the altruists who own all of it. Whether or not the altruists supply a positive amount of labor makes a big difference as to the incidence of alternative tax transfer policies.     

An internal control perspective on the market value consequences of IT operational risk events

IT internal controls are an important component of an organization's arsenal of internal controls. Upon conceptualizing failures of operational IT systems, or what we call IT operational risk events, as signals of IT internal control weaknesses, we theorize about these events' impact on internal control objectives in general and about how this impact is influenced by the regulatory environment in particular. We then perform an event study to examine the economic impact of a diversified sample of IT operational risk events from the U.S. financial services industry during 1985–2009. We specifically test the impact of contextual factors on the degree of this effect, including the events' target (confidentiality, integrity, or availability of IT assets), the source of disclosure (regulatory or voluntary), the enactment of the Sarbanes–Oxley Act, and firm-specific attributes. We find that investors penalize firms most strongly for experiencing events that compromise the availability of IT systems, consistent with our prediction that these events more negatively impact the reliability of financial reporting and the efficiency and effectiveness of operations. This result contrasts extant empirical studies that are predominantly concerned with information and security breaches. We find also that investors' penalty is the strongest for firms experiencing IT operational risk events that occurred after the passing of the Sarbanes–Oxley Act or were disclosed by a regulatory body. Finally, the market reaction is shown to be stronger for firms with high growth potential, firms that are larger, riskier, and are in the banking sector. Implications for research and practice are discussed along with directions for future research.     

A cross-cultural study of the persuasive effect of fear appeal messages in cigarette advertising: China and Canada

This exploratory study investigated the moderating influence of culture on the persuasive power of fear appeal advertisements differing on type of fear. The conceptual framework for the study was based on Rogers' Protection Motivation model and incorporated type of fear, physical and social, as an independent variable and culture as a moderating variable. An experiment was conducted on a sample of 173 Anglo-Canadian and 180 Chinese subjects. The findings revealed that the physical threat ads had a much greater effect on the Anglo subjects than on the Chinese. Most importantly, these ads brought about an attitude change for the Anglos, but not for the Chinese. For the social fear ads, contrary to predictions, only the Anglos reacted to the ads. They tended to score higher than the Chinese on attitude towards smoking as well as on behavioural intentions.     

Charts and demand: Empirical generalizations on social influence

Social influence on consumer behavior has long been a subject of academic research in various scientific fields. According to research by Salganik, Dodds, and Watts (2006), music demand is a function of social influence between consumers. Market concentration tends to increase when information on demand becomes publicly available. In addition, stochastic agglomeration caused by social influence decreases the predictability of market success. These heavily cited findings challenge traditional market research and provide important insights on the impact of social media and sales charts. We test the stability of their results by replicating the study on music demand in a slightly different setting. We further investigate the generalizability of findings by probing other product categories and different phases of purchase decisions, i.e., interest, consideration, and actual demand. Across all categories and across all dependent variables, we are able to replicate the direction of the effects. We do, however, consistently obtain smaller effect sizes than reported in the original paper.
