Estimating Labor Demand with Fixed Costs*

INTERNATIONAL ECONOMIC REVIEW, Issue 1 2004
Paola Rota
We consider a dynamic model in which firms decide whether or not to vary labor in the presence of fixed costs. By exploiting the first-order condition for optimality, we derive a semireduced form in which firms' intertemporal employment is defined by a standard marginal productivity condition augmented by a forward-looking term. We obtain a marginal productivity equilibrium relation that takes into account the future alternatives of adjustment or nonadjustment that firms face. We use the structural parameter from this condition to estimate the fixed cost within a discrete decision process. Fixed costs are about 15 months' labor cost. [source]

Risk-sensitive sizing of responsive facilities

NAVAL RESEARCH LOGISTICS: AN INTERNATIONAL JOURNAL, Issue 3 2008
Sergio Chayet
Abstract We develop a risk-sensitive strategic facility sizing model that makes use of readily obtainable data and addresses both capacity and responsiveness considerations. We focus on facilities whose original size cannot be adjusted over time and limits the total production equipment they can hold, which is added sequentially during a finite planning horizon. The model is parsimonious by design for compatibility with the nature of available data during early planning stages. We model demand via a univariate random variable with arbitrary forecast profiles for equipment expansion, and assume the supporting equipment additions are continuous and decided ex-post. Under constant absolute risk aversion, operating profits are the closed-form solution to a nontrivial linear program, thus characterizing the sizing decision via a single first-order condition. This solution has several desired features, including the optimal facility size being eventually decreasing in forecast uncertainty and decreasing in risk aversion, as well as being generally robust to demand forecast uncertainty and cost errors. We provide structural results and show that ignoring risk considerations can lead to poor facility sizing decisions that deteriorate with increased forecast uncertainty. Existing models ignore risk considerations and assume the facility size can be adjusted over time, effectively shortening the planning horizon. Our main contribution is in addressing the problem that arises when that assumption is relaxed and, as a result, risk sensitivity and the challenges introduced by longer planning horizons and higher uncertainty must be considered. Finally, we derive accurate spreadsheet-implementable approximations to the optimal solution, which make this model a practical capacity planning tool.© 2008 Wiley Periodicals, Inc.

Cointegration, Government Spending and Private Consumption: Evidence from Japan

THE JAPANESE ECONOMIC REVIEW, Issue 2 2004
Tsung-Wu Ho
Assuming a CRRA preference, this paper shows that there is a cointegration restriction implied by the intra-temporal first-order condition in the consumption function. This restriction predicts a cointegrated system of government consumption, private consumption, and their relative price. Our analysis indicates that, first, Johansen's VECM confirms the theoretical prediction that is supported by the data of Japan; moreover, Bierens' (1997) nonparametric estimator severely contradicts with the theoretical model and fits the data poorly; second, Japanese people have increasing willingness to rearrange their consumption over time. Besides, the intratemporal relationship between private and government consumption remains relatively stable over time. [source]

ENDOGENOUS COSTS AND PRICE-COST MARGINS: AN APPLICATION TO THE EUROPEAN AIRLINE INDUSTRY,

THE JOURNAL OF INDUSTRIAL ECONOMICS, Issue 3 2006
DAMIEN J. NEVEN
This paper allows for endogenous costs in the estimation of price cost margins. In particular, we estimate price-cost margins when firms bargain over wages. We extent the standard two-equation set-up (demand and first-order condition in the product market) to include a third equation, which is derived from bargaining over wages. In this way, price-cost margins are determined by wages and vice versa. We implement the model using data for eight European airlines from 1976,1994, and show that the treatment of endogenous costs has important implications for the measurement of price-cost margins and the assessment of market power. Our main result is that observed prices in Europe are virtually identical to monopoly prices, even though observed margins are consistent with Nash behavior. Apparently, costs had been inflated to the point that the European consumers were faced with a de facto monopoly prices. [source]

The Intratemporal Substitution between Government Spending and Private Consumption: Empirical Evidence from Taiwan

ASIAN ECONOMIC JOURNAL, Issue 3 2001
Ru-Lin ChiuArticle first published online: 18 DEC 200
In this paper, we investigate the idea that a general model of consumption should allow for the direct effect of government consumption. We show, given an assumed preference specification, that there is a cointegration restriction implied by an intraperiod first-order condition of the model. This restriction leads to a linear deterministic cointegrated system of government consumption, private consumption and their relative price that is consistent with the data for Taiwan. The intratemporal elasticity of substitution between government and private consumption is estimated to be about 1.1. Overall, we find consistent empirical evidence in support of our model. [source]

International dynamic risk sharing

JOURNAL OF APPLIED ECONOMETRICS, Issue 1 2008
Giuseppe Cavaliere
In this paper we examine the implications of international risk sharing among a set of countries in the presence of market frictions which complicate the instantaneous adjustment to the first-order conditions. We suggest approximating the consumption streams of countries belonging to the risk sharing coalition in terms of a disequilibrium dynamic model embodying forward-looking adjustment. Econometric methods for estimating and testing the model are discussed. Empirical analysis of a set of core European countries suggests that once preference parameters are allowed to vary across countries, we are able to identify a group of nations that share risks against idiosyncratic permanent income shocks. The equilibrium position, however, is reached after a long adjustment period. Copyright © 2008 John Wiley & Sons, Ltd. [source]

Efficient Allocations in Club Economies

JOURNAL OF PUBLIC ECONOMIC THEORY, Issue 1 2004
Marcus Berliant
We explore the characteristics of Pareto-optimal allocations in the context of local public goods or clubs. A set of first-order conditions for Pareto optimality is provided. Classical treatments apparently neglect an important term related to migrant compensation, and thus are incorrect. A Pareto optimum is shown to exist. [source]

POST-MERGER PRODUCT REPOSITIONING,

THE JOURNAL OF INDUSTRIAL ECONOMICS, Issue 1 2008
AMIT GANDHI
This paper analyzes the effects of mergers between firms competing by simultaneously choosing price and location. Products combined by a merger are repositioned away from each other to reduce cannibalization, and non-merging substitutes are, in response, repositioned between the merged products. This repositioning greatly reduces the merged firm's incentive to raise prices and thus substantially mitigates the anticompetitive effects of the merger. Computation of, and selection among, equilibria is done with a novel technique known as the stochastic response dynamic, which does not require the computation of first-order conditions. [source]
