The rise in comovement across national stock markets: market integration or IT bubble?

A stylized fact in the portfolio diversification literature is that diversifying across countries is more effective than diversifying across industries in terms of risk reduction. But with the rise in comovement across national stock markets since the mid-1990s, this no longer appears to be true. We explore if this change is driven by global integration and therefore likely to be permanent, or if it is a temporary phenomenon associated with the recent stock market bubble. Our results point to the latter hypothesis. In the aftermath of the bubble, diversifying across countries may therefore still be effective in reducing portfolio risk.     

Federal capital expenditures and budget deficits: Gross national product and labor implications

The issue of separating capital from operating expenditures has been largely ignored in discussions of the U.S. Federal Government's deficit. This paper attempts to overcome this void by conducting a simulation experiment designed to assess the macroeconomic consequences of separating capital from current expenditures under several alternative balanced budget rules and financing arrangements. The alternatives considered are directly related to management accounting issues and thus the purpose of this paper can be seen as compatible with the literature on the relationship between accounting techniques and economic analyses. The results of the study reaffirm the need for federal capital investment planning.     

Temporary immigration visas

This paper deals with recent proposals concerning temporary immigration visas as a means to combat the problem of illegal immigration. We set up a simple two-period model of international migration between a poor South and a rich North with temporary visas issued for one period. Because of capital market imperfections, immigrants from the South face additional capital costs when financing the visa fee. In this model, we find that temporary visas can improve welfare in the North if capital costs of the immigrants are sufficiently low. For high capital costs, however, a welfare reduction cannot be ruled out. We extend the model to the case of heterogeneous immigrants and asymmetric information. In this setting, we show that the government in the North may have an incentive to issue temporary visas for those with low capital costs and to tolerate illegal immigration of the others.     

The rise and rise of the share premium account

Share premiums now constitute a substantial proportion of UK company equity but rarely featured on nineteenth century company balance sheets. This paper discusses when and why this changed and why the definition of the share premium account as company capital took nearly a century to reach the statute books. From 1855 to 1948 any surplus above par on issued shares could be treated at the directors' discretion, including appropriation for the payment of dividends. This freedom was removed in the Companies Act 1948 (s. 56), after the Cohen Committee recommended that share premiums should normally be treated as share capital and employed in a very limited range of transactions. The paper outlines the accounting and legal history of the share premium account and argues that the growth of share premiums was due to a tax avoidance loophole, open from 1889 to 1973, which permanently changed company practice on share issues after 1920. The effect of legal restrictions on the use of the share premium account is also addressed. One possible future consequence of the loss of economic significance of the nominal value of a share is the total abolition of both this and the share premium account by adoption of no par value (npv) shares, a change which has recently been adopted in Australia and is again under consideration in the UK.     

The rise in student loan defaults

We examine the rise in student loan defaults in the Great Recession by linking administrative student loan data at the individual borrower level to student loan borrowers’ individual tax records. A Blinder-Oaxaca style decomposition shows that shifts in the composition of student loan borrowers and the massive collapse in home prices during the Great Recession can each account for approximately 30% of the rise in student loan defaults. Falling home prices affect student loan defaults by impairing individuals’ labor earnings, especially for low income jobs. By contrast, when comparing the default sensitivities of homeowners and renters, we find no evidence that falling home prices affect student loan defaults through a home equity-based liquidity channel. The Income Based Repayment (IBR) program introduced by the federal government in the wake of the Great Recession reduced both student loan defaults and their sensitivity to home price fluctuations, thus providing student loan borrowers with valuable insurance against negative shocks.
