This paper examines the distribution of income in Pakistan, and in each of its four provinces, from an explicit and formal Islamic perspective. A cardinally significant Atkinson-Kolm-Sen relative index of inequality reflecting that perspective is proposed and computed from the...

Arbitrage pressures that could equalize closed-end fund share prices with fund portfolio values appear to be largely absent in an extensive data set. Observed fund behavior violates the static arbitrage bounds of Gemmill and Thomas (2002) and is inconsistent with...

Previous papers find no relationship between interest rates and the discounts of US closed-end funds before 1985. This is taken as evidence against management fees being a cause of discounts because a negative relationship is expected: if interest rates rise...

It is commonly believed that firms prefer layoffs to worksharing, in part, because layoffs economize on fringe benefit costs. We find that when labor markets are characterized by optimal implicit contracts, layoffs will never occur in equilibrium, regardless of the...

This paper presents new results on income distribution in Pakistan from an analysis of the full HIES data tapes for 1984-85, 1985-86, 1986-87, and 1987-88. An explicit social welfare methodology is adopted to measure changes in inequality at the national...

There are numerous examples of assets with identical payout streams being priced differently. These violations of the law of one price result from two factors. First, investors have heterogeneous asset valuations so that if two groups of investors trade in...

Arbitrage positions that benefit from the reversion of closed-end fund discounts to rational levels show excess returns that increase in magnitude the more funds are mispriced. At the same time, fund trading volumes and bid-ask spreads more than double as...

The behavior of US closed-end funds is very different from that of the UK funds studied by Gemmill and Thomas (2002). There is no evidence that their discounts are constrained by arbitrage barriers, no evidence that higher expenses increase discounts...

Constant returns to scale, always a simplifying assumption, is often also much more: many important results depend critically on the very special properties of this class of production function. This paper provides a unified set of simple proofs for most...

Implicit contract models of labor market equilibrium under work sharing and layoffs are constructed to examine several common explanations for the observed market bias in favor of layoffs. We first establish the optimality of work sharing in the absence of...

The reaction of closed-end fund share prices to changes in portfolio values is on average the same whether funds are trading at discounts or premia and whether the changes in portfolio values are positive or negative. If closed-end fund discounts...

The larger a closed-end fund's premium over its portfolio value, the more intensely it is sold short. However, the intensity of short selling affects neither the rate at which premia mean revert to fundamental values nor the rate of return...

This paper argues that the degree to which a given industry's labor contracts are complete or incomplete is the major factor determining whether its workforce will be unionized. For instance, assembly line industries feature complete labor contracts because of the...

This paper presents empirical evidence on the extent to which zakat - a form of religiously-mandated charity under Islam - achieves its intended objective in Pakistan. Detailed income and expenditure data from Pakistan's Household Income and Expenditure Survey for 1987-88...
