WHICH FISCAL MULTIPLIERS ARE REGIME‐DEPENDENT? A META‐REGRESSION ANALYSIS

We analyse whether estimated multiplier effects are systematically higher if the economy suffers a downturn. For that purpose, we conduct a meta‐regression analysis on a unique data set of 98 empirical studies with more than 1800 observations on multiplier effects and control for regime‐dependence of the multiplier. We find that spending multipliers are much higher (by about 0.7–0.9 units) during a downturn. Tax multipliers are not sensitive to the economic regime, and generally lower than spending multipliers. Finally, for all spending categories other than government consumption, the multiplier significantly exceeds one during downturns.     

How a Firm's Domestic Footprint and Domestic Environmental Uncertainties Jointly Shape Added Cultural Distances: The Roles of Resource Dependence and Headquarters Attention

Even though many firms conduct most of their business domestically, international management research has remained remarkably silent on the role of a firm's domestic footprint in its internationalization strategy. We shed light on that role by exploring how the size of a firm's domestic footprint influences the cultural distance that the firm adds to its country portfolio when expanding internationally. Integrating resource dependence theory and the attention‐based view, we hypothesize that a firm's domestic footprint has a negative relationship with added cultural distance (ACD), and that domestic policy uncertainty strengthens this relationship whereas domestic demand uncertainty weakens it. We find robust support for our hypotheses in a sample of the world's largest retailers covering the period 2000–07, indicating that a firm's domestic footprint and domestic environmental uncertainties jointly shape cross‐cultural expansion strategies. Our findings suggest that ACDs reflect headquarters executives' desire to avoid ineffective foreign expansions, hinting at possible biases in studies of the performance effects of distance.     

Semiparametric time series regression modeling with a diverging number of parameters

Variable selection and error structure determination of a partially linear model with time series errors are important issues. In this paper, we investigate the regression coefficient and autoregressive order shrinkage and selection via the smoothly clipped absolute deviation penalty for a partially linear model with a divergent number of covariates and finite order autoregressive time series errors. Both consistency and asymptotic normality of the proposed penalized estimators are derived. The oracle property of the resultant estimators is proved. Simulation studies are carried out to assess the finite‐sample performance of the proposed procedure. A real data analysis is made to illustrate the usefulness of the proposed procedure as well.     

Concentration behavior of the penalized least squares estimator

Consider the standard nonparametric regression model and take as estimator the penalized least squares function. In this article, we study the trade‐off between closeness to the true function and complexity penalization of the estimator, where complexity is described by a seminorm on a class of functions. First, we present an exponential concentration inequality revealing the concentration behavior of the trade‐off of the penalized least squares estimator around a nonrandom quantity, where such quantity depends on the problem under consideration. Then, under some conditions and for the proper choice of the tuning parameter, we obtain bounds for this nonrandom quantity. We illustrate our results with some examples that include the smoothing splines estimator.     

Exports,Supply Constraints and Growth: An Investigation using Regional Data

In this work we first model the role of demand‐ and supply‐side factors (labour market adjustment, productive efficiency) in explaining economic growth. Empirically testing the model, we evaluate why different growth regimes may appear in the 20 Italian administrative regions. This exercise uses a two‐stage econometric approach. Estimates for the elasticity of manufacturing output to exports are obtained from regional time series: a significant long‐run relationship indicates the existence of a demand‐constrained growth regime. We then ascertain whether the regional dispersion of supply‐side factors has an impact on the regional dispersion of growth regimes. The empirical evidence supports our expectations of strong regional differences. Southern regions are less likely to display demand‐constrained regimes. In explanation of these differences, second‐stage analysis reveals that a strong role is played by such efficiency‐enhancing factors as technological innovation, bank diffusion and ‘social capital’. No role is found for labour market rigidities.     

Exchange Rate Pass‐through: The Role of Regime Changes

We consider the effect on the degree of exchange rate pass‐through of the exchange rate regime in operation. We test the hypothesis that pass‐through will be lower under a float as firms may be reluctant to pass appreciations or depreciations on to their customers when there is a strong chance that they will be subsequently reversed. Taylor’s hypothesis that pass‐through will be lower in a low‐inflation environment is also considered. Both hypotheses are assessed in relation to the price of manufactured imports into New Zealand and we find that, whereas the shift to a float dramatically lowered the degree of pass‐through, the later shift to a low‐inflation regime has no significant additional effect on the pass‐through relationship.     

Testing separability of public consumption in household decisions

In this paper we propose a sequential strategy, based on the microeconomic approach of the demand theory, in order to test for separability between private and public consumption. The aim of the present work is to verify, using a conditional almost ideal demand system, whether the different components of public consumption exert conditioning effects on the allocative structure of private spending. The empirical estimation of the model and the separability tests are developed for both a demand system in five functional categories of private spending, and for a demand system in six categories, where the private expenditures on those goods and services which can also be offered by the public sector are enclosed in a single functional category. The results of the separability tests, obtained using UK data for the 1974–2000 period, show that public individual consumption plays an important role in modifying consumer choices, while public collective consumption does not affect private consumption behaviours. The relationships between the different components of private spending and public individual consumption are both of substitutability and complementarity; in particular, we find that public individual consumption and the corresponding private expenditures on ‘Health, education, recreation and social protection’ are complements.     

Income and substitution effects of fiscal policy on work effort

The focus of this paper is twofold. First, it examines the impact on work effort of changes in government purchases financed with lump‐sum taxes, in a neoclassical framework, with respect to four industrialised countries. Second, it reconsiders the expenditure–work effort relationship in a broader conceptual context that allows for distortionary taxation and a disaggregation of the income and substitution effects. Our findings are shown to cast doubt on the empirical plausibility of the prevailing (neoclassical and New Keynesian) models which seem to rely heavily on the lump‐sum tax notion, thus ignoring the substitution effects of distortionary taxation.     

Gender differences in self‐employment

This paper examines the factors that influence transitions into self‐employment, paying particular attention to gender differences. We find that: (i) men are more responsive to the wage differential between wage/salaried employment and self‐employment; (ii) liquidity constraints are more important for men; and (iii) the link between father's self‐employment status and the probability of self‐employment is stronger for men. Taken together, these results suggest that, for women, self‐employment is a closer substitute for part‐time work and labour‐market inactivity than it is for men. We attribute such differences to the different labour market opportunities and occupational strategies of women.     

Shareholder Value Maximisation,Stock Market and New Technology: Should the US Corporate Model be the Universal Standard? 1

In 1992 a blue‐ribbon group of US economists led by Michael Porter concluded that the US stock market‐based corporate model was misallocating resources and jeopardising US competitiveness. The faster growth of US economy since then and the supposed US lead in the spread of information technology has brought new legitimacy to the stock market and the corporate model, which is being hailed as the universal standard. Two main conclusions of the analysis presented here are: (a) there is no warrant for revising the blue‐ribbon group’s conclusion; and (b) even US corporations let alone developing country ones would be better off not having stock market valuation as a corporate goal.
