Transaction costs and crop marketing in the communal areas of Impendle and Swayimana,KwaZulu-Natal

High transaction costs are detrimental to the efficient operation or existence of markets for inputs and outputs. The cost of information and the costs associated with the search for trade partners, the distance to formal markets and contract enforcement are likely to influence the marketing of food crops. This study hypothesises that the level of income generated from food-crop sales by small-scale farmers in the Impendle and Swayimana districts of KwaZuluNatal is influenced by transaction costs and certain household and farm characteristics. Regression analysis shows that the depth of marketing methods is significantly influenced by transaction cost proxies, such as cooperation with large commercial farmers and ownership of means of transport. Results from a block-recursive regression analysis show that the level of crop income generated is determined by the depth of marketing methods, the size of allocated arable land and off-farm income. Households with lower transaction costs, sizeable allocated land and off-farm income can be expected to generate higher income from food crops. Investment in public goods such as roads, telecommunications and an efficient legal system (to uphold commercial contracts), as well as farmer support services (input supply, extension, marketing information and research), would probably raise farm and non-farm income by reducing transaction costs. This would increase the effective demand for locally produced goods and services, thus contributing to rural employment and livelihoods within rural communal areas.     

Erstens: ignorieren, zweitens: diffamieren, drittens: umarmen?

Mass media are an essential factor for the success of small parties, for the media can act in a supporting or an inhibiting way towards these parties. This could be observed for the example of the German Green Party: As the Greens were becoming more and more important in the parliaments, the media changed their formerly very critical view of the party to a more factual and positive reporting. Is the party “Die Linke” now experiencing a similar process? The present study analyses the comments of three national German newspapers from 2005 to 2009, using a quantitative content analysis with the aim of bringing to light how the media acted towards “Die Linke”. The results show that commenting has hardly changed since earlier studies were published. Factual issues only play a marginal role, and the party is judged negatively in all newspapers, with the tageszeitung slightly distinct from the other two papers, though.     

A Classification of Dutch Manufacturing based on a Model of Innovation

Summary The paper studies the degree of homogeneity of innovative behavior in order to determine empirically an industry classification of Dutch manufacturing that can be used for policy purposes. Defining homogeneity in terms of an economic model distinguishes our classification from existing taxonomies such as those of the OECD, Pavitt and the various classifications based on a principal components analysis. We use a two-limit tobit model with sample selection, which explains the decisions by business enterprises to innovate and the impact these decisions have on the share of innovative sales. The model is estimated for eleven industries based on the Dutch Standard Industrial Classification (SBI 1993). A likelihood ratio (LR) test is then performed to test for equality of the parameters across industries. We find that Dutch manufacturing consists of three groups of industries in terms of innovative behavior, a high-tech group, a low-tech group and the industry of wood. The same pattern shows up in the three Dutch Community Innovation Surveys. The empirical part of this study has been carried out at the Centre for Research of Economic Microdata at Statistics Netherlands.

On structural inelasticity of modal substitution in freight transport

At the European level there is an increasing focus on how freight transport can be moved from trucks on roads to more environmentally friendly modes such as rail and ship. A large proportion of the transport services between OD pairs, however, cannot be substituted since there is only one alternative available. The paper investigates the magnitude of this “structural inelasticity” of modal substitution in freight transport due to a sparser layout of rail and ship-based freight networks compared to road. In the analysis we use a recent Scandinavian freight demand model covering more than 800 zones. We find that the structural inelasticity is very significant - in particular for transportation over less than 500 km. Moreover, the inelasticity varies greatly with commodity groups and between OD pairs, and it depends strongly on the port and rail infrastructure. The results suggest that pure charging instruments (road pricing for trucks) in many regions will have limited mode substitution impacts. However, if combined with structural changes in terms of improved infrastructure for rail and ship, impacts may be greater.     

The effect of alternative goals on earnings management studies: An earnings benchmark examination

Firms’ management manages earnings because they have incentives or goals to do so. Earnings management studies have to account for these different goals as tests of earnings management can be compromised by the effect of conflicting goals. I illustrate this in the setting of Dechow et al. (2003). Their study examines whether firms with small profits and firms with small losses (loss-avoidance benchmark) have differing levels of discretionary accruals. Dechow et al. (2003) find that firms just above the loss-avoidance benchmark do not have discretionary accruals that are significantly different than firms just below the benchmark. However, they do not consider firms just below the loss-avoidance benchmark that might be using discretionary accruals to avoid missing an alternative benchmark. I find that after I consider these alternate earnings benchmark goals, firms just above the benchmark have significantly higher discretionary accruals. This provides direct evidence that the ‘kink’ in the distribution of earnings arises from earnings management. I find similar results for the earnings changes benchmark. These findings highlight the need to consider alternative earnings benchmark goals when examining firms immediately around benchmarks.     

Repeated interaction in standard setting

Standardization may allow the owners of standard‐essential patents to charge higher royalties than would have been negotiated ex ante. In practice, however, standard‐setting efforts are often characterized by repeated interaction and complementarities among technologies. These features give firms that contribute technology to standards both the ability and the incentive to avoid excessive royalties by threatening to exclude other technology contributors from future rounds of standardization if they charge royalties exceeding ‘fair, reasonable, and nondiscriminatory’ (FRAND) levels. We show that such an outcome can be sustained as a subgame‐perfect equilibrium of a repeated standard‐setting game and examine how the decision‐making rules of standard‐setting organizations (SSOs) affect the sustainability of FRAND royalties. Our analysis provides a novel justification for super‐majority requirements and other rules frequently adopted by SSOs.     

Costos del despido y ventajas de la medición con métodos directos

Es frecuente achacar los malos resultados del mercado laboral a los costos del despido y a las normas que rigen las relaciones de trabajo. Ahora bien, las investigaciones acerca de las consecuencias económicas de los despidos prestan muy poca atención a la calidad y la precisión de las mediciones, y no arrojan indicaciones concluyentes. Después de pasar revista a los métodos actuales de medición, el autor sostiene que es muy conveniente usar métodos cuantitativos directos a fin de complementar las mediciones indirectas habituales. Para ilustrar esta afirmación se vale de una encuesta efectuada recientemente en Australia.     

THEORY AND EVIDENCE IN PSYCHOLOGY AND ECONOMICS ABOUT MOTIVATION CROWDING OUT: A POSSIBLE CONVERGENCE?

The empirical relevance of motivation crowding out is a controversial issue in economics and psychology. As already pointed out by Frey and Jegen ( 2001 ), this is partly due to the historical development of two distinct and parallel strands of literature that stem from different theoretical traditions, have radically different tenets and therefore, are difficult to reconcile. In this survey, we go back to the details of the debates that took place independently among psychologists and economists, and sketch an integrative interdisciplinary approach likely to favor a more fruitful collaboration between economics and psychology. From this perspective, experimental economics (both field and laboratory) is viewed as a major research field shedding new light on the conditions of relevance of motivation crowding out.     

Jointly Optimal Taxes and Enforcement Policies in Response to Tax Evasion

Assuming the government cannot fully observe either individual types or incomes and jointly picks optimal taxes and audit policies against evasion can significantly alter standard results from optimal income taxation and tax‐evasion models, which treat these separately. We consider this when individuals differ in their risk preferences and incomes. Given the resulting complexity, supplementing analytic results with numerical analysis helps explain the structure of the resulting policies and how they change when the distribution of income or the revenue requirements of the government change. We do this analysis with and without audit errors and with incomes exogenous or affected by occupational choice.
