Beyond conjoint analysis: Advances in preference measurement

We identify gaps and propose several directions for future research in preference measurement. We structure our argument around a framework that views preference measurement as comprising three interrelated components: (1) the problem that the study is ultimately intended to address; (2) the design of the preference measurement task and the data collection approach; (3) the specification and estimation of a preference model, and the conversion into action. Conjoint analysis is only one special case within this framework. We summarize cutting edge research and identify fruitful directions for future investigations pertaining to the framework’s three components and to their integration.     

Capitalizing on Franchisee Autonomy: Relational Forms of Governance as Controls in Idiosyncratic Franchise Dyads*

Franchisee autonomy not only fosters system‐wide adaptability and outlet owners' satisfaction but also raises the costs from agency problems present in franchisee–franchisor dyads. Advancing upon the understanding of agency issues involved in franchising, we test the argument that chains counterbalance the loss in control inherent to autonomy with relational governance mechanisms. The empirical results provided strong support for this presumption. In addition, and most notably, we found that the more relational governance becomes important, the weaker agents' incentives are aligned with the interests of the entire network. The moderating effects of five franchisee characteristics influencing goal congruencies were considered: multiunit ownership, age of the relationship, geographic distance, franchisee success, and the level of perceived intra‐chain competition. Implications for chain management are provided.     

Fixed-Reimbursement Insurance: Basic Properties and Comparative Statics

In a number of settings, insurance contracts specify a fixed reimbursement in the event of a loss which is not conditioned on the size of the realized loss. In this article, we explore the theoretical properties of this form of insurance and draw comparisons with other types of insurance policies, such as those based on coinsurance and deductibles. We also examine links between our results and those from the literature on precautionary saving.     

Curvature and the elasticity of substitution: Straightening it out

This paper demonstrates that, contrary to deeply rooted beliefs, there is no link between curvature and the elasticity of substitution. We show that there is no direct, nor inverse, relationship between the two concepts, if curvature of the isoquant is defined either in its strict mathematical sense or as the isoquant's second derivative. We finally suggest to view the elasticity of substitution as an efficiency parameter.     

TRADE POLICY AND MARKET POWER: FIRM‐LEVEL EVIDENCE

This article identifies the effect of trade policy on market power through new data and a new identification strategy. We identify market power by observing how exporting firms price discriminate across markets following variations in bilateral exchange rates. Pricing‐to‐market is prevalent in all countries in our sample, even among small firms, although it is increasing in firm size. More importantly, we find that the effect of nontariff measures (NTMs) is not isomorphic to that of tariffs. Whereas tariffs reduce the market power of foreign firms through rent‐shifting effects, NTMs reinforce the market power of nonexiting firms, domestic and foreign alike.     

Comparing inequality aversion across countries when labor supply responses differ

We analyze to which extent social inequality aversion differs across nations when controlling for actual country differences in labor supply responses. Towards this aim, we estimate labor supply elasticities at both extensive and intensive margins for 17 EU countries and the US. Using the same data, inequality aversion is measured as the degree of redistribution implicit in current tax-benefit systems, when these systems are deemed optimal. We find relatively small differences in labor supply elasticities across countries. However, this changes the cross-country ranking in inequality aversion compared to scenarios following the standard approach of using uniform elasticities. Differences in redistributive views are significant between three groups of nations. Labor supply responses are systematically larger at the extensive margin and often larger for the lowest earnings groups, exacerbating the implicit Rawlsian views for countries with traditional social assistance programs. Given the possibility that labor supply responsiveness was underestimated at the time these programs were implemented, we show that such wrong perceptions would lead to less pronounced and much more similar levels of inequality aversion.     

Computing minimal state space recursive equilibrium in OLG models with stochastic production

Using order-theoretic methods, we derive sufficient conditions for the existence, characterization, and computation of minimal state space recursive equilibrium (RE), as well as Stationary Markov equilibrium (SME) for various classes of stochastic overlapping generations models. In contrast to previous work, our methods focus on constructive methods. Our existence results are obtained for models that include public policy (e.g., social security policies, transfers, taxes, etc), production nonconvexities, elastic labor supply, non-monotone income processes, and long-lived agents. We distinguish conditions under which there exist various subclasses of minimal state space RE, including bounded, monotone, non-monotone, semicontinuous, Lipschitz continuous RE. Finally, we provide monotone equilibrium comparative statics results on the space of economies for some RE.     

Exchange rate pass-through in Turkish export and import prices

This article investigates the effects of horizontal acquisitions on the performance of target firms in the 1990s. Using French manufacturing firm-level data, we examine two main indicators of performance: the profit and the productive efficiency. We distinguish domestic from cross-border acquisitions. To evaluate the impact of take-overs, we implement appropriate difference-in-difference estimation techniques associated to a matching propensity score procedure. We find that Mergers &?Acquisitions (M&A) do not increase the profit of French target firms, even on the long run. However, they clearly raise the productivity of target firms. These results suggest that firms probably redistribute efficiency gains at the upstream and/or downstream production stage. There is no evidence of an increase in market power. In addition, the consequences of domestic and cross-border M&A significantly differ. Efficiency gains are stronger for cross-border M&A. This conclusion is however true only for extra-European Union operations. The achievement in the European economic integration certainly explains the absence of difference between European and domestic acquisitions. Finally, our results cast some doubt on the frequent discrimination attitude towards foreign takeovers and the fears of their impact on firms’ performance and the host country's welfare.     

On the Price of Risk Under a Regime Switching CGMY Process

In this paper, we study option pricing under a regime-switching exponential Lévy model. Assuming that the coefficients are time-dependent and modulated by a finite state Markov chain, we generalise the work in Momeya and Morales (Method Comput Appl Probab, 2014, doi: 10.1007/s11009-014-9399-2), and Siu and Yang (Acta Mathe Appl Sin 2:369–388, 2009), that is, we use a pricing method based on the Esscher transform conditional on the information available on the Markov chain. We also carry out numerical analysis, to show the impact of the risk induced by the underlying Markov chain on the price of the option.
