Identity Work: Sustaining Transnational Collective Action at General Motors Europe

What are the conditions under which transnational collective action is initiated and sustained? This article presents a case study of General Motors Europe, where labor leaders have mobilized the workforce and bargained with management at the transnational level repeatedly over more than a decade as a response to management whipsawing and threats of plant closures. In contrast to structuralist interest‐based theories of union behavior, we identify a process of “identity work” that was necessary to sustain transnational worker cooperation.     

ELECTORAL CYCLES THROUGH LOBBYING

In this paper, we build a framework where the interplay between the lobby power of special interest groups and the voting power of the majority of the population leads to political business cycles. We apply our setup to explain electoral cycles in government expenditure composition, aggregate expenditures, and real exchange rates.     

Optimal Monetary Policy with Countercyclical Credit Spreads

We study optimal monetary policy in a New‐Keynesian Dynamic Stochastic General Equilibrium (DSGE) model with a credit channel and relationship lending in banking. We show that borrowers' bank‐specific (deep) habits give rise to countercyclical credit spreads, which, in turn, make optimal monetary policy depart substantially from price stability, under both discretion and commitment. Our analysis shows that the welfare costs of setting monetary policy under discretion (with respect to the optimal Ramsey plan) and of using simpler suboptimal policy rules are strictly increasing in the magnitude of deep habits in credit markets and market power in banking.     

Intrinsic Persistence of Wage Inflation in New Keynesian Models of the Business Cycles

We derive and estimate a New Keynesian wage Phillips curve that accounts for intrinsic inertia. In line with microevidence on wage setting, we consider a wage‐setting model featuring an upward‐sloping hazard function, based on the notion that the probability of resetting a wage depends on the time elapsed since the last reset. Our wage Phillips curve embeds also backward terms. We test the hazard function slope using generalized method of moment estimation. Then, placing our equation in a small‐scale New Keynesian model, we investigate its dynamic properties using Bayesian estimation. Model comparison shows that our model outperforms commonly used alternative methods to introduce persistence.     

Short‐Term Corporate Debt around the World

Short‐term corporate debt as a proportion of total debt issued by public firms varies greatly across countries, between 28% in the United States and 78% in China. This paper argues that the interaction between information asymmetry and legal protection of creditors is an important determinant of debt maturity. When short‐term debt plays a dual role as signaling and commitment devices, a reduction in information asymmetry has a larger impact on debt maturity when creditor rights are weaker. We find empirical support for this prediction using firm‐level data from 45 countries around the world.     

Imperfectly Credible Disinflation under Endogenous Time‐Dependent Pricing

The real effects of an imperfectly credible disinflation depend critically on the extent of price rigidity. We examine this interaction in a model with endogenous time‐dependent pricing. Both the endogenous initial degree of price rigidity and changes in the duration of price spells during disinflation are important in explaining the effects of imperfect credibility. We initially consider a setup where the degree of credibility is fixed and then allow agents to update beliefs about the “type” of monetary authority that they face. In both cases, the interaction between endogeneity of pricing behavior and imperfect credibility increases the output costs of disinflation.     

The Swing Voter's Curse in the Laboratory

This paper reports the first laboratory study of the swing voter's curse and provides insights on the larger theoretical and empirical literature on "pivotal voter" models. Our experiment controls for different information levels of voters, as well as the size of the electorate, the distribution of preferences and other theoretically relevant parameters. The design varies the share of partisan voters and the prior belief about a payoff relevant state of the world. Our results support the equilibrium predictions of the Feddersen–Pesendorfer model. The voters act as if they are aware of the swing voter's curse and adjust their behaviour to compensate. While the compensation is not complete and there is some heterogeneity in individual behaviour, we find that aggregate outcomes, such as efficiency, turnout and margin of victory, closely track the theoretical predictions.     

NONLINEAR PRICING IN ASYMMETRIC DUOPOLY

We characterise, for both separate and interdependent markets, the local pure-strategies Nash equilibrium of a spatial duopoly game, where consumers are horizontally and vertically heterogeneous, and firms have different cost structures and ranges of product lines. We show that standard results which emerged in the monopoly context can not be generalised to strategic contexts where firms retain market power and there is sufficient competitive pressure. We prove that in the asymmetric duopoly case, when markets are interdependent, the incentive compatibility constraints are slack, and there is no quality distortion.     

IS CORPORATE R&D INVESTMENT IN HIGH‐TECH SECTORS MORE EFFECTIVE?

This paper discusses the link between R&D and productivity across the European industrial and service sectors. The empirical analysis is based on both the European sectoral OECD data and on a unique micro‐longitudinal database consisting of 532 top European R&D investors. The main conclusions are as follows. First, the R&D stock has a significant positive impact on labor productivity; this general result is largely consistent with previous literature in terms of the sign, the significance, and the magnitude of the estimated coefficients. More interestingly, both at sectoral and firm levels the R&D coefficient increases monotonically (both in significance and magnitude) when we move from the low‐tech to the medium‐ and high‐tech sectors. This outcome means that corporate R&D investment is more effective in the high‐tech sectors and this may need to be taken into account when designing policy instruments (subsidies, fiscal incentives, etc.) in support of private R&D. However, R&D investment is not the sole source of productivity gains; technological change embodied in gross investment is of comparable importance on aggregate and is the main determinant of productivity increase in the low‐tech sectors. Hence, an economic policy aiming to increase productivity in the low‐tech sectors should support overall capital formation.
