The socio-economic impact of certification schemes in conflict-affected regions: The case of arabica coffee in the Eastern DRC

The paper investigates the benefits of certification of cooperatives in conflict-affected areas. We study whether and how certification may contribute to attenuate the impact of conflicts on the members of coffee cooperatives in the Eastern DRC. We use an inverse probability weighted difference-in-difference approach to study data collected between December 2017 and October 2019 from four NGO-supported cooperatives. Two of these cooperatives got organic certification in 2018, of which one got an additional Small Producers Symbol (SPP) certification in 2018. Certified cooperatives allow Arabica coffee producers to access markets and buffer against drops in market prices. Results indicate that certified cooperatives were better able to resist the international price drop than non-certified cooperatives and the alternative informal markets. The results also suggest that certified cooperative members increased their sales to the cooperative instead of turning to informal side-selling. We find a decrease in reported food deficits by the members of certified cooperatives and an increase in the importance of coffee in their household's income. We conclude that certification is an effective way forward for smallholder coffee producers and cooperatives in unstable regions.     

Accept–reject Metropolis–Hastings sampling and marginal likelihood estimation

We describe a method for estimating the marginal likelihood, based on Chib (1995) and C hib and Jeliazkov (2001) , when simulation from the posterior distribution of the model parameters is by the accept–reject Metropolis–Hastings (ARMH) algorithm. The method is developed for one-block and multiple-block ARMH algorithms and does not require the (typically) unknown normalizing constant of the proposal density. The problem of calculating the numerical standard error of the estimates is also considered and a procedure based on batch means is developed. Two examples, dealing with a multinomial logit model and a Gaussian regression model with non-conjugate priors, are provided to illustrate the efficiency and applicability of the method.     

Discretion vs. timeless perspective under model-consistent stabilization objectives

Recent literature has reported situations in which discretion dominates timeless perspective in the presence of elements that reduce the slope of the New Keynesian Phillips curve. Considering a model-consistent welfare metric inhibits this mechanism in the standard New Keynesian framework.     

Profiling potential green electricity tariff adopters: green consumerism as an environmental policy tool?

Green electricity tariffs are one means by which green consumers can contribute to a more sustainable future. This paper profiles potential adopters of green electricity tariffs. Potential adoption is measured in terms of respondents' willingness to pay a premium for green energy in a national survey of the UK population. Hypotheses based principally on the cognitive–behavioural literature on green consumerism and green energy markets are developed. These are tested using a broad range of variables, which are grouped into three categories (demographic, attitudinal and behavioural). Consistent with past research, the empirical analyses find that attitudinal variables best characterize potential adopters. Further, potential adopters are found to have higher income, be better informed with respect to energy matters, show concern for the environment and believe that individual actions can make a difference to environmental decay. The implications of these findings for marketing and environmental policy are explored. Copyright © 2010 John Wiley & Sons, Ltd and ERP Environment.     

True and fair in the Czech Republic: a note on local perceptions

With the collapse of communism in Czechoslovakia’, and the subsequent desire of Czechoslovakia to join the European Union, in common with other countries in Central Europe, Czechoslovakia utilized the Fourth Directive as a ‘toolkit’ in designing part of its new accounting legislation. In incorporating the Fourth Directive, it has also included the requirement for financial statements to show a ‘true and fair’ view. Given the confusion over the exact meaning of ‘true and fair’ it is interesting to study how ‘true and fair’ has been introduced into the Czech Republic, and what it seems to signify for those who implemented it and for those who are preparing and using financial statements. Our initial findings indicate that ‘true and fair’ varies in its significance for the groups of individuals involved in preparing and using financial statements and that it may have particular significance for some groups of accountants who wish to secure specific advantage within the Czech economy.With the collapse of communism in Czechoslovakia’, and the subsequent desire of Czechoslovakia to join the European Union, in common with other countries in Central Europe, Czechoslovakia utilized the Fourth Directive as a ‘toolkit’ in designing part of its new accounting legislation.

A Political Economy Application of the “Tragedy of the Anticommons”: The Greek Government Debt Crisis

The tragedy of the anticommons unfolds when separate social agents—be they private owners of a property who intend to use the property for their own economic benefit or political actors who pursue their political objectives—do not hold effective rights to use their economic or political power for their own purposes without consent of the other players of the economic or political game. I shall discuss the Greek government debt crisis and the Eurozone countries’ policies toward Greece within the analytical framework of the tragedy of the anticommons in this paper. I do not intend to dig deep into the structure and long-term trends of public and private finances in Greece. I shall only show that the successive bail-out programs of the Eurozone countries were doomed to fail because of these countries’ competitive and non-cooperative approach to the Greek financial problems. I shall also show that a coordinating agency, say the IMF, can foster the coordinated outcome only under strict informational conditions.     

Trade Liberalization and Heterogeneous Technology Investments

We propose a trade model where heterogeneous firms decide on a productivity‐enhancing technology investment. The model analyzes the impact of multilateral trade liberalization on firm‐ and industry‐level productivity. Freer trade increases the incentives to invest in technology by raising export profits. It also dampens these incentives, however, as profits stemming from domestic sales are reduced. Only exporters benefit from the former positive effect. The shape of the distribution of efficiency draws, the level of trade costs and the technology intensity of the industry are key elements removing the ambiguities regarding the net impact of trade liberalization.     

Design beyond complexity: Possible futures—Prediction or design? (and techniques and tools to make it possible)

This paper is an attempt to discuss the concepts of complexity and complex social system and their relation with the concepts of design and design activity. It is argued that a design cannot appear as an emergent property out of such systems, since it presupposes intentionality. However, to a certain extent, complex (social) systems need to be governed by means of design. Even if design requires prediction, which in our opinion is impossible in strict sense in case of social systems, there are two important conditions for a “good design”, namely, to look at the past, and to look at the future. After this general discussion, the paper provides a few suggestions on how to do the former without prejudices, and presents an effective technique for doing the latter without illusions.     

一种转型理论

在这篇短评中,我将对孙立平富有启发性的文章,“社会转型：发展社会学的新议题”,做些补充而不是批评。我对孙的文章大都同意,我不想详细讨论我们之间多数是在术语使用上的分歧,而想强调我们在分析上的共同点。
