Evaluating the Economic Significance of Downward Nominal Wage Rigidity

This paper seeks to contribute to the literature on downward nominal wage rigidity (DNWR) along two dimensions. First, we formulate and solve an explicit model of wage-setting in the presence of worker resistance to nominal wage cuts - something that has previously been considered intractable. In particular, we show that this resistance renders wage increases (partially) irreversible. Second, using this model, we can explain why previous estimates of the macroeconomic effects of DNWR have been so weak despite remarkably robust microeconomic evidence. In particular, we show that previous studies have neglected the possibility that DNWR can lead to a compression of wage increases as well as decreases. Thus, the literature may have been overstating the costs of DNWR to firms. Using micro-data for the US and Great Britain, we find robust evidence in support of the predictions of the model. In the light of this evidence, we conclude that increased wage pressure due to DNWR may not be as large as previously envisaged, but that the data is nevertheless consistent with a model in which workers resist nominal wage cuts.Nominal Wage Rigidity, Loss Aversion, Irreversibility

Marginal Jobs, Heterogeneous Firms, & Unemployment Flows

This paper introduces a notion of fir m size into a search and matching model with endogenous job destruction. The outcome is a rich, yet analytically tractable framework that can be used to analyze a broad set of features of both the cross section and the dynamics of the aggregate labor market. In a set of quantitative applications we show that the model can provide a coherent account of a) the salient features of the distributions of employer size, and employment growth across establishments; b) the amplitude and propagation of cyclical fluctuations in flows between employment and unemployment; c) the negative comovement of unemployment and vacancies in the form of the Beveridge curve; and d) the dynamics of the distribution of employer size over the business cycle.

The Role of Worker Flows in the Dynamics and Distribution of UK Unemployment

Unemployment varies substantially over time and across subgroups of the labour market. Worker flows among labour market states act as key determinants of this variation. We examine how the structure of unemployment across groups and its cyclical movements across time are shaped by changes in labour market flows. Using novel estimates of flow transition rates for the UK over the last 35 years, we decompose unemployment variation into parts accounted for by changes in rates of job loss, job finding and flows via non-participation. Close to two-thirds of the volatility of unemployment in the UK over this period can be traced to rises in rates of job loss that accompany recessions. The share of this inflow contribution has been broadly the same in each of the past three recessions. Decreased jobfinding rates account for around one-quarter of unemployment cyclicality and the remaining variation can be attributed to flows via non-participation. Digging deeper into the structure of unemployment by gender, age and education, the flow-approach is shown to provide a richer understanding of the unemployment experiences across population subgroups.labour market, unemployment, worker flows

The great recession in the UK labour market : a transatlantic perspective

The increase in unemployment in the United Kingdom that accompanied the Great Recession has been conspicuous by its moderation. The rise in joblessness is dwarfed by the recent experience of the United States, by past recessionary episodes in the U.K. and by the contraction in GDP in the U.K. Increased rates of job loss have played a dominant role in shaping the rise in British unemployment. Unemployment duration has not increased to the levels seen in previous recessions, in contrast to the U.S. where duration substantially exceeds previous peaks. Looking forward, the U.K. labour market appears to have adjusted fully to the shocks that prompted the recession. Signs of reductions in match efficiency witnessed recently in the U.S. are not mirrored in the U.K. In contrast, while long-term unemployment currently remains well below historical levels, recent estimates of job finding rates suggest that it has the potential to rise much further. Thus, a timely recovery in aggregate demand will play an important role in averting persistently high unemployment in the future

Population growth, immigration and labour market dynamics

This paper examines the role of population flows on labour market dynamics across immigrant and native-born populations in the United Kingdom. Population flows are large, and cyclical, driven first by the maturation of baby boom cohorts in the 1980s, and latterly by immigration in the 2000s. New measures of labour market flows by migrant status uncover both the flow origins of disparities in the levels and cyclicalities of immigrant and native labour market outcomes, as well as their more recent convergence. A novel dynamic accounting framework reveals that population flows have played a nontrivial role in the volatility of labour markets among both the UK-born and, especially, immigrants

Stepping Off the Wage Escalator: The Effects of Wage Growth on Equilibrium Employment

This paper emphasizes the role of wage growth in shaping work incentives. It provides an analytical framework for labor supply in the presence of a return to labor market experience and aggregate productivity growth. A key finding of the theory is that there is an interaction between these two forms of wage growth that explains why aggregate productivity growth can affect employment rates in steady state. The model thus speaks to an enduring puzzle in macroeconomics by uncovering a channel from the declines in trend aggregate wage growth that accompanied the productivity slowdown of the 1970s to persistent declines in employment. The paper also shows that the return to experience for high school dropouts has fallen substantially since the 1970s, which further contributes to the secular decline in employment rates. Taken together, the mechanisms identified in the paper can account for all of the increase in nonemployment among white male high school dropouts from 1968 to 2006. For all white males, it accounts for approximately one half of the increase in the aggregate nonemployment rate over the same period.

Cell Cycle Phase Regulates Glucocorticoid Receptor Function

The glucocorticoid receptor (GR) is a member of the nuclear hormone receptor superfamily of ligand-activated transcription factors. In contrast to many other nuclear receptors, GR is thought to be exclusively cytoplasmic in quiescent cells, and only translocate to the nucleus on ligand binding. We now demonstrate significant nuclear GR in the absence of ligand, which requires nuclear localisation signal 1 (NLS1). Live cell imaging reveals dramatic GR import into the nucleus through interphase and rapid exclusion of the GR from the nucleus at the onset of mitosis, which persists into early G1. This suggests that the heterogeneity in GR distribution is reflective of cell cycle phase
