Wage and employment effects of a wage norm

Most transition countries used tax‐supported wage norms in the early 1990s, as a part of their market liberalization programmes. This article analyses how a firm‐level tax (or subsidy) on deviations from a pre‐set wage norm may promote employment by rotating the labour demand curve perceived by the workers’ union around the value of the norm. We derive the conditions under which it yields a positive employment effect. We test the effect of the norm on the wages on a sample of Polish firms in 1990 and 1991. The data support the role of the wage norm on the position of the perceived labour demand curve and the role of the tax rate on its slope.     

Optimal growth and cycles in overlapping generations models

Summary This paper investigates the dynamical properties of optimal paths in one-sector overlapping generations models without assuming that the utility function of the representative agent is separable. When the utility function is separable, the optimal growth paths monotonically converges toward the modified golden rule steady state. In the non-separable case, we show that the optimal growth path may be oscillating and optimal two-period cycles may exist. Applying these results to the model with altruism, we show that the condition of operative bequest is fully compatible with endogeneous fluctuations provided that the discount factor is close enough to one. All our results are illustrated using Cobb-Douglas utility and production functions.We thank C. Blackorby, J. Blot, P. Cartigny and one anonymous referee for helpful comments and suggestions which generally improved the exposition of the paper.

Household Behavior with Imperfect Labor Markets

A household model with differential asset endowments and idiosyncratic transactions costs in accessing labor markets is developed to (1) explain membership of farm households to alternative labor regimes (sellers, employers, or self-sufficient in labor), (2) test for recursivity between production and consumption decisions selectively by labor regime, and (3) identify the determinants of differential labor productivity across labor regimes. The model is applied to a 1994 household survey of the Mexican land reform sector.     

Proposals for a Minimum Programme for Statistics in Developing Countries

Statistical offices in developing countries are confronted with the challenge of introducing, with limited means, methods and tools ensuring the production of durable statistics satisfying regional, national and international requirements. Taking into account the evolution, over the last years, in the attitude of national authorities, funding partners and statisticians themselves regarding the building up of relevant and durable statistics, the present paper's proposal is to have, in each developing country, a Minimum Programme for Statistics (MPS) and that this programme be centred on four domains: coordination, national accounts, economic and social short term analysis, and dissemination.     

Voluntary firm restructuring: why do firms sell or liquidate their subsidiaries?

This paper examines why companies decide to divest a subsidiary in a corporate environment characterised by concentrated ownership, using a unique dataset of non-listed Belgian subsidiaries. The results of the binomial logit analyses are consistent with the idea that management will intervene in order to improve the controlling firm’s focus or when subsidiary performance imposes a burden on the group’s financial situation. Especially when blockholders hold more than 75% of the shares, these motives drive the divestiture decision. At lower levels of ownership concentration, these hypotheses cannot explain the higher divestiture likelihood, which supports the agency hypothesis. Once the divestment decision has been taken, the choice has to be made between a sale and liquidation. The logit analysis reveals that although selling a subsidiary seems the preferred option, liquidation is likely when the subsidiary is small, active in a sector with few competitors and when financial distress is eminent.     

Asset pricing models with errors-in-variables

This paper revisits Fama and French [Fama, Eugene F., French, Kenneth R., (1993) Common risk factors in the returns on stock and bonds. Journal of Financial Economics 33 (1), 3–56] and Carhart [Carhart, Mark M., 1997. On persistence in mutual fund performance. Journal of Finance 52 (1), 57–82] multifactor model taking into account the possibility of errors-in-variables. In their well known paper, Fama and French [Fama, Eugene F., French, Kenneth R., 1997. Industry costs of equity. Journal of Financial Economic 43 (2), 153–193] concluded that estimates of the cost of equity for the three-factor model of FF (1993) were imprecise. We argue that this imprecision is even more severe because of the pervasive effects of measurement errors. We propose Dagenais and Dagenais [Dagenais, Marcel G., Dagenais, Denyse L., 1997. Higher moment estimators for linear regression models with errors in the variables. Journal of Econometrics 76 (1–2), 193–221] higher moments estimator as a solution. Our results show that estimates of the cost of equity obtained with Dagenais and Dagenais estimator differ sharply from popular OLS estimates and shed a new light on performance attribution and abnormal performance (α). Adapting the Generalized Treynor Ratio, recently developed by Hübner [Hübner, Georges, 2005. The generalized treynor ratio. Review of Finance 9 (3), 415–435], we show that the performance of managed portfolios with multi-index models should be revisited in presence of errors-in-variables.     

REAL OPTIONS WITH COMPETITION AND REGIME SWITCHING

In this paper, we examine irreversible investment decisions in duopoly games with a variable economic climate. Integrating timing flexibility, competition, and changes in the economic environment in the form of a cash flow process with regime switching, the problem is formulated as a stopping‐time game under Stackelberg leader‐follower competition, in which both players determine their respective optimal market entry time. By extending the variational inequality approach, we solve for the free boundaries and obtain optimal investment strategies for each player. Despite the lack of regularity in the leader's obstacle and the cash flow regime uncertainty, the regime‐dependent optimal policies for both the leader and the follower are obtained. In addition, we perform comprehensive numerical experiments to demonstrate the properties of solutions and to gain insights into the implications of regime switching.     

What is the added value of an organic label? Proposition of a model of transfer from the perspective of ingredient branding

ABSTRACT

This paper investigates the added value of an organic ingredient strategy and the transfer mechanisms at work when placing an organic label on product brands. We proposed and empirically tested an integrated model that included three stages: brand and label equity; transfer mechanisms; and product evaluation. We first selected an organic label and product brands and then tested our hypotheses with a sample of French consumers. The results confirm the positive influence of brand and label equity on transfer mechanisms (brand/label perceived fit and ease of transfer) and, in turn, illustrate how ease of transfer influences the overall product evaluation. A surprising result is that brand/label perceived fit does not directly affect the overall product evaluation; rather, it only influences brand/label ease of transfer.
