Unemployment rate hysteresis and the great recession: exploring the metropolitan evidence

Standard unit-root tests of the hysteresis hypothesis specify a unit root under the null against the stationary alternative of the natural-rate hypothesis,

The evolution of conventions in minimum effort games

The literature on minimum effort game has been concerned with a symmetric game with linear payoff functions. The main aim of the present paper is to study the coordination problem arising in a not necessarily symmetric minimum effort game with two players. The sources of asymmetry can be twofold: the productivity of effort and the distribution of the join output. To select among the Pareto ranked equilibria we use the stochastic stability criterion. We show that, for any configuration parameters, the set of stochastically stable equilibria coincides with the set of potential maximizers. We also show that when the disutility of effort is linear, the Pareto dominant equilibrium is stochastically stable provided that the distributive parameter belongs to a well defined range. When the disutility of effort is nonlinear no distributive arguments can be used to successfully affect the selection process. Lastly we prove that the connection between stochastic stability and maximum potential can fail when more than two agents are considered.     

Advertising effect on primary demand: a cointegration approach

This paper addresses the question of the effects of advertising on the primary demand for whisky in Italy. In contrast to previous works, this issue is investigated in a multivariate framework by referring to Johansen's cointegration technique; this choice allows the non-stationary dynamics of aggregate marketing data to be taken into account, as well as their short-term and long-term relationships. Even if advertising is linked to real prices and sales in the long run, our analysis reveals no evidence supporting the effectiveness of advertising on the aggregate demand for whisky, which is essentially determined by the real price, both in the short and the long term.     

Directed hypergraphs as a modelling paradigm

We address a generalization of graphs, the directed hypergraphs, and show that they are a powerful tool in modelling and solving several relevant problems in many application areas. Such application areas include Linear Production Problems, Flexible Manufacturing Systems, Propositional Logic, Relational Databases, and Public Transportation Systems.     

Corporate hierarchy, promotion, and firm growth: Japanese internal labor market in transition

This paper investigates the incentive systems and the hierarchical design of the Japanese firms as integral parts of employment structure. Using the survey cross-section data on job ranks and wages, we analyze the promotion policy and compensations system as the key incentive mechanism in these firms with highly developed internal labor markets. We find that the incentive as well as hierarchical structures of the large Japanese firms are highly sensitive to the longrun growth rates of these firms. This finding is supported by a prediction of a model of internal promotions developed in the paper. We also find that the span of control, incentive effects of promotion, and wage-age profile at each job rank are all increasing in the longrun growth rates of these firms. These findings are jointly consistent with and in support of the hypothesis that the expected gains from the promotion is the key incentive in inducing efforts of the employees.     

Random utility demand models and service location

This paper considers the problem of the optimal location of facilities when the demand behavior is described by a random utility choice model. By means of duality theory of mathematical programming, it is shown how a wide family of such problems can be mapped into an entropy maximizing problem, which is usually easy to solve numerically. Theory and methods are discussed in details for the problem of locating a single type of facilities, and the extension to some kinds of systems with many types of facilities is outlined.
