Immigrant assimilation pre and post labour market entry: evidence from the UK Labour Force Survey

We estimate models of employment an earnings for a sample of white and non-white male immigrants drawn from the Labour Force Survey between 1993 and 2004. Immigrants who arrived to enter the labour market (labour market entrants) are distinguished from those who arrived to complete their education (education entrants). Diverse patterns of labour market assimilation are found depending on ethnicity and immigrant type. Amongst labour market entrants, whites do better than non-whites, whilst amongst education entrants, highly qualified prime-age non-whites perform as well as their white counterparts. Relative to white natives, labour market outcomes for all immigrant groups have a tendency to decline with age.

CORPORATE TAX POLICY AND INDUSTRY LOCATION WITH FULLY ENDOGENOUS PRODUCTIVITY GROWTH

This paper considers how national corporate tax policy affects productivity growth through adjustments in geographic patterns of industry in a two‐country model of trade. With trade costs and imperfect knowledge spillovers between countries, production concentrates partially and innovation concentrates fully in the country with the lowest tax rate. A rise in the international corporate tax differential accelerates productivity growth through an increase in the production share of the low‐tax country that improves knowledge spillovers from industry to innovation. The paper also investigates the relationship between the corporate tax differential and the level of market entry, and analytically characterizes the effects of changes in tax policy on national welfare.

Equilibrium Wage‐Tenure Contracts

In this study we consider a labor market matching model where firms post wage‐tenure contracts and workers, both employed and unemployed, search for new job opportunities. Given workers are risk averse, we establish there is a unique equilibrium in the environment considered. Although firms in the market make different offers in equilibrium, all post a wage‐tenure contract that implies a worker's wage increases smoothly with tenure at the firm. As firms make different offers, there is job turnover, as employed workers move jobs as the opportunity arises. This implies the increase in a worker's wage can be due to job‐to‐job movements as well as wage‐tenure effects. Further, there is a nondegenerate equilibrium distribution of initial wage offers that is differentiable on its support except for a mass point at the lowest initial wage. We also show that relevant characteristics of the equilibrium can be written as explicit functions of preferences and the other market parameters.     

Linking Objectives to Actions: A Decision Support Approach Based on Cause–Effect Linkages

The process of translating objectives into actions is a difficult task. This difficulty is due to the wide range of possibilities and the lack of structured information. Managers must take into account relevant information and generate a range of options before a decision is reached. So far, little is available to guide managers in translating a set of objectives into actions. This paper presents a three‐stage action‐planning process to address this gap. The process, supported by a software tool, takes managers through the stages of model building, action generation, and action evaluation and selection. A case study illustrates the application of the process. The paper concludes by discussing the implication of this work for managers and academics.     

Transformation: Canadian Social Policy Since 1985

This paper sets out to document and explain the major structural changes which have taken place in Canada's social security system since the mid-1980s. Most major programs have been cut back one way or another, in response to a combination of pressures. Foremost amongst these has been the commitment to reduce federal and provincial government deficits. In addition there have been the consequences of high unemployment and increasing job insecurity, demographic and social changes, and "tax fatigue" on the part of the public. The paper documents major recent changes of social policy both in general—with regard to the changed approach evident at federal level and its effect on social transfers to the provinces—and in respect of key programs, including unemployment/employment insurance, old age pensions/the Canada Pension Plan, and child benefits. The paper next identifies "currents and undercurrents" common to all of the developments commented on: the decline of universality, the practice of "social policy-making by stealth", the evidence of the contemporary Canadian public's "collective ambivalence and loss of memory" in respect of the major, historic social programs. It concludes by urging the case for social reinvestment in genuinely sustainable social policy, in the currently more favourable fiscal climate.     

Shame and Guilt in Men Exposed to Childhood Sexual Abuse: A Qualitative Investigation

This study examined the experiences of shame and guilt in adult males sexually abused as children. Seven participants attending a service for male sexual abuse completed measures of shame, guilt, dissociation, and childhood trauma history and subsequently participated in a focus group. All participants experienced childhood sexual abuse in the “severe” range and showed elevated scores for shame, guilt, and dissociation. Four superordinate themes with associated subordinate themes emerged: (a) self-as-shame (foundations of self-as-shame, fear of exposure, temporary antidote: connection), (b) pervasiveness and power of doubt and denial (from others, from self, consequences of incredulity), (c) uncontrollability (of problems after disclosure, of rage, of intrusions and emotional pain), and (d) dissociation. Results are discussed with reference to the existing literature and the emerging “self-as-shame” construct, which appeared to encapsulate participants’ view of themselves.
