The inverse amplitude method is used to unitarize the two-loop pp scattering amplitudes of SU~2! chiral perturbation theory in the I50,J50,I51,J51, and I52,J50 channels. An error analysis in terms of the low energy one-loop parameters l̄ 1,2,3,4 and existing experimental data is undertaken. A comparison to standard resonance saturation values for the two-loop coefficients b̄1,2,3,4,5,6 is also ca...

We use time series techniques to estimate the importance of four main explanations for decline US labor income share: rising firm markups, falling bargaining power workers, higher investment-specific technology growth, and more automated production processes. Identification is achieved with restrictions derived from a stylized model structural change. Our results point automation as driver shar...

Wage Gaps Large and Small The law of one wage does not strictly hold, nor should it be expected to hold, in contemporary labor markets. The law of one wage, however, provides a surprisingly good first approximation of the structure of U.S. wages. This generalization is drawn from research on a diverse set of topics: the Mincerian wage equation and earnings imputation, union wage differentials, ...

Rent extraction by public sector workers may be limited by the ability of taxpayers to vote with their feet. But rent extraction may be higher in regions where high amenities mute the migration response. This paper develops a theoretical model that predicts such a link between public sector wage differentials and local amenities, and the predictions are tested by analyzing variation in these di...

Does union membership increase sickness absence from work and, if so, by how much? And which specific channels does this effect operate through? Using UK Labour Force Survey data for 2006-2008 we find that trade union membership is associated with a substantial increase in the probability of reporting sick and in the amount of average absence taken. This result can be largely attributed to the ...

In this paper we use British Household Panel Survey data to examine the relationship between unionization and unpaid overtime in Britain. The findings indicate that in the for-profit, non-caring sector of the economy, union covered employees supply fewer unpaid overtime hours than noncovered ones due to union protection and the weakening of economic incentives caused by union bargaining. On the...

This paper studies a strategic aspect of pro t-sharing in an oligopolistic industry with a monopoly union. Whenever a uniform pro t share exists in the industry, we show that a union that values the per worker remuneration positively, may have incentives to reduce industry employment, decreasing thus total output and causing total pro ts to increase. Thus, we show that pro t-sharing may lead to...

The magnetic sublevel specific preparation of the uX Sg 1 ,v51,J51& state of molecular H2 using stimulated Raman pumping with circularly polarized light to saturate the Q01(1) transition is reported. The intensities of S branch rotational Raman scattering signals for the v50 and v51 states combined with their depolarization ratios measured as a function of pumping light polarization provide dir...

This paper explains why some employees who favor unionization fail to join, and why others who wish to abandon union membership continue paying dues. Our explanation is based on a model where employees incur switching (search) costs when attempting to abandon (acquire) union membership. Empirical analysis for Britain confirms one of the main predictions from the switching-cost-model that segmen...

This paper constructs a political equilibrium in which firms and unions bargain over wages and workers and capitalists lobby the government for taxation, labor market regulation and immigration policy. The main findings are the following. It is in the native workers’ interests to ban firms’ direct recruitment from abroad. Otherwise, the ruling elite captures the surplus of the labor unions by t...
