An Experimental Bribery Game

Essential characteristics of corruption are (1) reciprocityrelationships between bribers and public officials, (2) negativewelfare effects, and (3) high penalties when discovered. Weseparate the influences of these factors in an experiment. Ina two-player game, reciprocation is economically inefficientthrough negative externalities. A control treatment withoutexternalities is also conducted. In a third, so-called suddendeath treatment, corrupt pairs face a low probability of exclusionfrom the experiment without payment. The results show that reciprocitycan establish bribery relationships, where negative externalitieshave no apparent effect. The penalty threat significantly reducescorruption, although discovery probabilities are typically underestimated.

Prioritising land to be preserved for agriculture: A context-specific value tree

In Belgium as in many other countries, agricultural land is under pressure for development of other land uses. This paper presents a method for setting priorities for preservation of land for agriculture. The method is based on a participatory approach through which a value tree is formulated. This results in a list of criteria to define farmland value, which is explicitly linked to the objectives for farmland preservation. The value tree allows the list of criteria to be determined in a structured and consistent way. The participatory process contributes to the development of a shared vision on farmland preservation. The approach also incorporates context specificity, as shown by its application for farmland preservation in Flanders.     

The effects of (incentivized) belief elicitation in public goods experiments

Belief elicitation is an important methodological issue for experimental economists. There are two generic questions: 1) Do incentives increase belief accuracy? 2) Are there interaction effects of beliefs and decisions? We investigate these questions in the case of finitely repeated public goods experiments. We find that belief accuracy is significantly higher when beliefs are incentivized. The relationship between contributions and beliefs is slightly steeper under incentives. However, we find that incentivized beliefs tend to lead to higher contribution levels than either non-incentivized beliefs or no beliefs at all. We discuss the implications of our results for the design of public good experiments.     

ASEAN and China: Export Rivals or Partners in Regional Growth?

Rivalry in trade between China and its regional neighbours in ASEAN has become a major preoccupation for many regional policy‐makers. For these reasons, strengthening the basis of empirical evidence on regional trade relations is especially important, and this paper does so in two ways. Using very detailed historical trade data, we combine econometric and trade flow analysis to elucidate patterns of export competition and underlying comparative advantage for ASEAN and China. Our findings indicate that the potential exists for both export rivalry and more extensive trade complementarity, but so do many challenges for policy makers who seek to mitigate adjustment costs and facilitate long term efficiency. Our econometric results indicate that, in the short run at least, ASEAN and China are experiencing intensified export competition in prominent third markets such as Japan and the US. More extensive trade flow analysis reveals, however, that in the long run globalisation can accommodate export growth by all the economies of East Asia, if aggregate growth can be sustained to facilitate the structural adjustments necessary for an optimal regional division of labour.     

Can fat taxes and package size restrictions stimulate healthy food choices?

Consumers prefer bonus packs, as opposed to price discounts, for healthy foods, but they want a price discount rather than a bonus pack for indulgent foods (Mishra & Mishra, 2011). This study conceptually replicates and extends this finding to show that consumers are more responsive to changes in price than to changes in package size for indulgent food options, whereas they are more responsive to changes in package size than to changes in price for healthy food options.     

Corporate sustainability and innovation in SMEs: Evidence of themes and activities in practice

Recently, innovation processes towards sustainable development have received increasing attention in academic literature. This research introduces the combination of insights from innovation theory, sustainable development practice and small business characteristics to unlock new knowledge on factors that influence the translation of sustainable innovation within small and medium‐sized enterprises (SMEs) into practice. The sustainability themes and activities as described for large companies (i.e. in the sustainability reporting and management literature) were used as starting point in this study. It presents empiric results of the PRIMA Project conducted within the rubber and plastics industry (RPI) on sustainable innovation activities. It will show that many sustainable innovations are directed at the improvement of technological processes (eco‐efficiency) and to lower costs of production. These innovations can be seen as incremental. Companies with sustainability integrated in their orientation and innovation processes show value creation: the development of products new to the market (radical innovations) and cooperation with stakeholders. The PRIMA project shows that more insight in SME innovative characteristics and (e)valuation of sustainable innovation efforts provides opportunities to improve the sustainability performance of SMEs.

On Conformity Testing and the Use of two Stage Procedures

Conformity testing is a systematic examination of the extent to which an entity conforms to specified requirements. Such testing is performed in industry as well as in regulatory agencies in a variety of fields. In this paper we discuss conformity testing under measurement or sampling uncertainty. Although the situation has many analogies to statistical testing of a hypothesis concerning the unknown value of the measurand there are no generally accepted rules for handling measurement uncertainty when testing for conformity. Usually the objective of a test for conformity is to provide assurance of conformity. We therefore suggest that an appropriate statistical test for conformity should be devised such that there is only a small probability of declaring conformity when in fact the entity does not conform. An operational way of formulating this principle is to require that whenever an entity has been declared to be conforming, it should not be possible to alter that declaration, even if the entity was investigated with better (more precise) measuring instruments, or measurement procedures. Some industries and agencies designate specification limits under consideration of the measurement uncertainty. This practice is not invariant under changes of measurement procedure. We therefore suggest that conformity testing should be based upon a comparison of a confidence interval for the value of the measurand with some limiting values that have been designated without regard to the measurement uncertainty. Such a procedure is in line with the recently established practice of reporting measurement uncertainty as “an interval of values that could reasonably be attributed to the measurand”. The price to be paid for a reliable assurance of conformity is a relatively large risk that the procedure will fail to establish conformity for entities that only marginally conform. We suggest a two‐stage procedure that may improve this situation and provide a better discriminatory ability. In an example we illustrate the determination of the power function of such a two‐stage procedure.     

Estimating transport costs and trade barriers in China: Direct evidence from Chinese agricultural traders

Using a unique survey data on agricultural traders in China in 2004, this study provides direct evidence on the significance of inter-regional trade barriers and their key components. Our major findings are as follows. (1) The trade barriers within China are fairly small, accounting for about 20% of trade value. (2) Transport and non-transport costs respectively contribute 42% and 58% to the trade barriers. (3) Labor and transport-related taxes are the two largest proportions of total transport costs, and respectively account for 35% and 30%. (4) Artificial trade barriers created by the government are not sizable as we perceived. (5) Road quality is crucial for reducing transport costs within China: increasing transport speed by 1 km per hour, the total transport costs for Chinese agricultural traders would decrease by 0.6%, mainly due to improved fuel-burning efficiency and reduced labor requirement.
