THE EMPLOYER SIZE-WAGE EFFECT: CAN DYNAMIC MONOPSONY PROVIDE AN EXPLANATION?

In this paper we argue that a dynamic monopsony model (basedon labour market frictions) predicts a positive relationshipbetween wages and employer size, but also that the effect willbe larger in the non-union sector than in the union sector,and larger for women than for men. We examine evidence on theemployer size-wage effect using several microeconomic data sources,and find it to be generally consistent with these predictions.After examining other theoretical explanations, our conclusionis that at least part of the employer size-wage effect is aresult of monopsony power in the labour market.     

MAY ISSUE VERSUS SHALL ISSUE: EXPLAINING THE PATTERN OF CONCEALED-CARRY HANDGUN LAWS, 1960–2001

We analyze the timing and pattern of adoption of "shall issue" concealed-carry handgun laws. "Shall issue" laws require the authorities to issue permits to qualified applicants; "may issue" laws give the authorities more latitude to reject applications. We find three factors influence the shift from "may issue" to "shall issue." First, more urban states are less likely to shift to "shall issue," although the size of this effect is quantitatively small. Second, the switch is influenced by the decisions taken by neighboring states. Third, we find evidence that increases in the crime rate accelerated the switch to "shall issue." ( JEL K40)     

Lost Exceptionalism? Comparative Income and Productivity in Australia and the UK, 1861–1948*

Australia had one of the highest per capita incomes in the world in the late nineteenth century, although this exceptional position subsequently eroded over time. This paper compares national income and sectoral labour productivity in Australia and the UK between 1861 and 1948 to uncover the underlying sources of Australia's high income and the reasons for its subsequent relative decline. We find that the country's higher per capita income was due primarily to higher labour productivity, because labour force participation, although higher in Australia than in the USA, was lower than in the UK. Australia had a substantial labour productivity lead in agriculture throughout the period, due to the importance of high value-added, non-arable farming, and a smaller lead in industry before World War I. The early productivity lead in industry was largely based on the importance of mining, and disappeared as manufacturing became more important. There was little productivity difference in services. These results reaffirm the importance of Australia's successful exploitation of its natural resource endowments in explaining the country's high initial income.     

WELFARE LOSS OF WETLANDS DISINTEGRATION: A LOUISIANA STUDY

This study estimates the loss in welfare of projected Louisiana coastal wetlands disintegration. Various programs have initiated costly projects to terminate this disintegration process. But can these projects succeed, and will their benefits exceed their costs? This study addresses the benefits issues and estimates reductions in incomes and consumption opportunities and increases in costs that would be avoided if restoration and enhancement projects are successful. Estimated welfare losses that would be avoided do not include non-user and lifestyle losses, which may be very important, and they do not include the costs of dismantling coastal infrastructure. These exclusions make the estimates of this study minimum estimates of welfare losses. Future economic welfare losses represent a 1990 present value in a range between $5.9 and $24.3 billion, depending upon discount rates and whether low or high loss estimates are used. In order to make these estimates more meaningful, the implied wetlands values were calculated on a per acre basis. These values ranged from $8,437 to $15,763 per acre.     

Personal Lending Relationships

I identify the effects of personal relationships on loan contracting using executive deaths and retirements at other firms as a source of exogenous variation in executive turnover. After plausibly exogenous turnover, borrowers choose lenders with which their new executives have personal relationships 4.1 times as frequently, and loans from these lenders have 20 basis points lower spreads and 12.5% larger amounts. Personal relationships benefit firms across loan terms, especially during macroeconomic downturns. Increased financial flexibility from personal relationships insulated firms from financial shocks during the recent financial crisis: they exhibited less constrained investment and were less likely to layoff employees.
