Counterintuitive number effects in experimental oligopolies

Recent theoretical research on oligopolistic competition suggests that under certain conditions prices increase with the number of competing firms. However, this counterintuitive result is based on comparative-static analyses which neglect the importance of dynamic strategies in naturally-occurring markets. When firms compete repeatedly, supra-competitive prices can become sustainable but this is arguably more difficult when more firms operate in the market. This paper reports the results of laboratory experiments investigating pricing behavior in a setting in which (static) theory predicts the counterintuitive number effect. Under a random matching protocol, which retains much of the one-shot nature of the model, the data corroborates the game-theoretic prediction. Under fixed matching duopolists post substantially higher prices, whereas prices in quadropolies remain very similar. As a result, the predicted effect is no longer observed, and towards the end the reverse effect is observed.

20 years of stated preference valuation of non-timber benefits from Fennoscandian forests: A meta-analysis

Stated preference (SP) surveys have been conducted to value non-timber benefits (NTBs) from forests in Norway, Sweden and Finland for about 20 years. The paper first reviews the literature and summarises methodological traditions in SP research in the three countries. Second, a meta-regression analysis is conducted explaining systematic variation in Willingness-to-Pay (WTP). Two important conclusions emerge, with relevance for future research: (1) WTP is found to be insensitive to the size of the forest, casting doubt on the use of simplified WTP/area measures for complex environmental goods; and (2) WTP tends to be higher if people are asked as individuals rather than on behalf of their household.     

Brand-anchored discrete choice experiment (BDCE) vs. direct attribute rating (DAR): An empirical comparison of predictive validity

The image of a brand provides a key driver of brand equity. To build and control a strong brand image though, brand managers require a valid procedure to measure it. This article empirically compares the predictive validity of two measurement techniques to assess brand image: First, a brand-anchored discrete choice experiment (BDCE) which is based on a brand-anchored conjoint approach where brands serve as the levels for any attribute and which was originally introduced as ranting-based approach by Louviere and Johnson Journal of Retailing, 66, 359–382 (1990) and further extended to a BDCE by Eckert et al. International Journal of Research in Marketing, 29, 256–264 (2012). Second, a direct attribute rating (DAR) approach which is commonly used for commercial applications of brand image measurement. An empirical study using a representative sample of the German beer market shows that BDCE shows significantly higher levels of predictive validity (i.e., higher correlations with the actual market shares of the brands under investigation) than the widely used DAR method.     

Multinational enterprises and wage costs: vertical FDI revisited

This study explores how wage costs for high-skilled and less-skilled labor in host countries affect the level of affiliate activities conducted by foreign MNEs. We find support for vertical FDI, in the sense that more FDI is conducted in countries where less-skilled labor is relatively cheap. In addition, we find that skilled-wage cost premia also affect FDI activities previously associated with horizontal FDI, i.e. local affiliate sales. Consequently, the potential effects of relative wage costs on MNE activities are large. Rough calculations suggest that more than 20 percent of US affiliate sales in 1998 can be attributed to skilled-wage cost premia.     

Image feedback effects of brand extensions: Evidence from a longitudinal field study

This paper examines the issue of image feedback effects and potential drivers of these effects by analyzing real-world extensions that have been introduced successfully in the market, using a longitudinal field study. Within the context of typical FMCG extensions, the authors find strong evidence that even for successful extensions, negative image feedback effects can occur, particularly when the perceived quality of the extension fails to meet the quality level of the parent brand. Strong brands tend to be more vulnerable to negative image feedback effects because consumers have a higher reference level for their extensions than for those of weaker brands. The likelihood of negative feedback effects decreases as the level of perceived fit and consumers’ perceptions of the general extendibility of the parent brand increases. But managers cannot, at least in the short run, mitigate negative image feedback effects through increased advertising support. Finally, the findings demonstrate that the feedback effects of a new extension product on parent brand image diminish over time.

Monetary and fiscal policy interactions in a micro-founded model of a monetary union

This paper analyzes in detail the mechanisms behind fiscal stabilization policy and the role of policy commitment in a micro-founded New-Keynesian model of a two-country monetary union, which is hit by supply shocks. We also explore the determinants of the gains from fiscal stabilization. While monetary policy with identical union members is concerned with stabilizing the union-wide economy, fiscal policy aims at stabilizing inflation differences and the terms of trade. Besides exploring optimal policies, we also consider monetary and fiscal rules. We study these rules both under coordination and non-coordination by the fiscal authorities.     

BLOCOS URBANISM: Capitalism and Modularity in the Making of Contemporary Luanda

In this article we portray and unpack the fabric of urban expansion in contemporary Luanda. In doing so, we examine interdependencies and complementarities between the organization of oil extraction off the coast of Angola, the emergence of particular modalities of modernist city planning for the expansion of its capital city, and the proliferation of cement blocks in the making of new urban forms throughout its burgeoning peripheries. By showing how urban development has unfolded through the interconnected realization of multiple kinds of systematizing blocks—namely oil blocks, city blocks and cement blocks—we analyse key material components in the production of new markets and urban spaces in the Angolan capital. By tracing forms of capitalism and modularity in the making of contemporary Luanda, we develop the concept of blocos urbanism to draw attention to modes of standardization and the production of legibility in contemporary processes of urbanization. Through this study, we aim to contribute to the conceptual apparatus for deciphering our global urban condition.

Do asylum-seekers respond to policy changes? Evidence from the Swedish–Syrian case*

Do asylum-seekers respond to policy changes in their destination country, and to what extent? We approach this question by using high-frequency data, and we focus on a sudden liberalization in Swedish policy toward Syrian asylum-seekers, which implied permanent instead of temporary residence. We show a clear and fast, yet temporary, increase in Syrian asylum applications in Sweden after the policy change. Also, the policy caused a shift – not limited to the short term – in the share of individuals arriving without family, and consequently in the share applying for family reunification. Our study adds quasi-experimental evidence to the literature on inter-country asylum flows and migration policy.
