Shedding “light” on marriage: The influence of skin shade on marriage for black females

The inter-racial marriage gap that opened in the past 50 years is generally attributed to a decline in the availability of young black marriageable men. We contend that the associated shortage of desirable men in the marriage market provides those black men who are sought after with the opportunity to attain a high status spouse, which has placed a premium on black women with lighter skin. We provide evidence, based on data drawn from the Multi City Study of Urban Inequality, consistent with this hypothesis. Our theoretical analysis of the marriage market reveals that marriage promotion policies to increase the desire to marry on the part of young black women will serve to exacerbate the importance attached to skin shade.     

An on-line intellectual community or “MEMEX” revisited

This paper represents one individual's view of the potential impact of Computer and Information Science technology on the future of scientific and technical information transfer. However, the propositions put forth are based upon a synthesis of existing efforts tempered by what seem to be the most significant needs in the current process.

The paper attempts to piece together how current efforts in abstract services, journal and book publication, word processing, computerized conferences, and information retrieval systems may ultimately evolve as a single system serving the needs of the scientific and technical community.     

At the crossroads of “futurism” and “prospective”: Towards a Canadian synthesis?

North American “future studies” and the French concept of “prospective” have been integrated to provide the basis for an attempted “Canadian Synthesis” in the approach developed by the Montreal-based think-tank, the Gamma Institute. In this paper the founding president of Gamma outlines the four stages of the approach in a conceptual framework entitled the “Chronospace” and illustrates its applicability by referring to some of Gamma's projects in the last 12 years.     

An Evaluation of Batra's “Fallacy of Free Trade”*

Batra (1992) argues that international trade since 1972 has lowered the living standards of most Americans (whose income results from providing labor services), while benefiting the small group of capital owners. This commentary shows that Batra's arguments are based on incorrect data and that his analyses are grossly lopsided. Batra further claims that the manufacturing base of the United States is shrinking due to international trade and that, therefore, this sector should be protected. the facts, however, counter Batra's contention, thereby dealing a fatal blow to his policy recommendation. This commentary refutes several additional assertions in Batra's paper.     

Ecological Intuition versus Economic “Reason”

This paper discusses the discount rate to be used in projects aimed at preserving the environment. The model has two different goods: one is the usual consumption good whose production may increase exponentially, and the other is an environmental good whose quality remains limited. The stylized world we describe is fully determined by four parameters, reflecting basic preferences, “ecological” and intergenerational concerns, and feasibility constraints. We define an ecological discount rate and examine its connections with the usual interest rate and the optimized growth rate. We discuss, in this simple world, different forms of the precautionary principle.     

WHY SMALL GROUPS AND LOW INCOME SECTORS OBTAIN SUBSIDIES: THE “ALTRUISTIC” SIDE OF A “SELF-INTERESTED” GOVERNMENT*

We develop a model of political support seeking politicians and support supplying voters. Based on Downs' original formulation, the framework yields endogenous political weights with both liberal and conservative properties. Our model reconciles the apparent contradiction between models of self-interested politicians and of governments motivated by social concerns. We show that the “altruistic” aspect of government behavior is consistent with its “self-interested” behavior. We determine that the Olson-Becker pressure group model is not unique. An increase in deadweight costs reduces the equilibrium subsidy. Smaller groups receive a larger per capita subsidy. These results are consistent with Becker's model.     

Eating like which “Joneses?” an Iterative Solution to the Choice of a Poverty Line “Reference Group”

A standard method for calculating poverty lines (e.g. Ravallion, 1994) is not fully specified. The choice of the "reference population" for determining food baskets is left to the decision of the individual analyst. However, the poverty line can be quite sensitive to the real income of the reference group because the "quality" of the food basket—measured as the food expenditures per calorie—rises sharply with income. We propose that the reference group be centered on the poverty line. To address the obvious circularity problem in choosing a reference population at the poverty line to define the poverty line, we use an iterative approach. This iterative method provides a methodological anchor that fixes the reference group.     

Crime and Punishment and Corruption: Who Needs “Untouchables?”

Becker's result that fines should be maximized is also applicable to some social environments where law enforcers are corrupt. If the regulated activity is legal, the principal may efficiently deter crime without an anti‐corruption unit. An opportunistic anti‐corruption unit, even when corrupt, becomes useful for the principal when the activity is illegal, since the principal's goal of maximizing fines motivates the unit to collect bribes from the enforcer, which subsequently induces the enforcer to be nearly completely honest, minimizing corruption. Therefore, we show that there is not necessarily an infinite regress originating with the puzzle of who polices the police.     

“Expiration hour effect of futures and options markets on stock market” — A case study on NSE (National Stock Exchange of India)

This paper studies the effect of expiration day of the Index futures and Options on the trading volume, variance and price of the underlying shares. The impact of derivatives trading on the underlying stock market has been widely documented in the Finance literature. In particular, significant differences in the statistical properties of asset returns (for instance, mean and variance) during expiration and non-expiration days have been advanced as an evidence for the destabilization effect (or lack there of) of derivative instruments. The earlier studies have, however, drawn their conclusions without rigorously modelling the underlying stochastic data generation process. Given that the statistical properties mentioned before are merely traits of the asset returns, this approach can lead to spurious results if analyzed in isolation of the underlying process. We propose to address this crucial shortcoming by examining the expiration day effect from a GARCH (Generalized Auto Regressive Conditional Heteroskedastic) framework. We use both daily and high frequency (5 min and 10 min) data on S&P CNX Nifty Index. Our central finding using intra-day data is that while there is no pressure – downward or upward – on index returns, the volatility is indeed significantly affected by the expiration of contracts. This effect, however, doesn’t show up in daily data.     

Efficiency with Non-Convexities: Extending the “Scandinavian Consensus” Approaches

There are two distinct “Scandinavian consensus” approaches to public good supply, both based on agents' willingness to pay. A Wicksell–Foley public competitive equilibrium arises from a negative consensus in which no change of public environment, together with associated taxes and subsidies which finance it, will be unanimously approved. Alternatively, in a Lindahl or valuation equilibrium, charges for the public environment induce a positive consensus. To allow general non-convexities to be regarded as aspects of the public environment, we extend recent generalizations of these equilibrium notions and prove counterparts to both the usual fundamental efficiency theorems of welfare economics.     

ON THE KING-DAVENANT “LAW” OF DEMAND1

“Now there is one law of prices which you must know and understand before you can make the least progress in interpreting the simplest problem. It is known to some economists, I do not say all, for it is most unaccountably neglected or obscured in most treatises on the subject, as Gregory King's Law.”     

Accumulative pollution, “clean technology,” and policy design

This paper addresses the optimal long-term management of an accumulative but assimilable pollutant through economic incentive policies that restrict more damaging production processes and induce more benign alternatives. Using a simple general equilibrium approach, we consider the possibility that the assimilative capacity of the environment is eventually exhausted by pollution accumulation. In this case, there is a nonconvexity in the problem that gives rise to multiple potential optima; environmental quality may be preserved or completely degraded in the long term. We characterize the circumstances under which phasing out dirty production is consistent with an intertemporally optimizing path and we discuss the design of price-based and quantity-based policies for supporting an optimal solution with the nonconvexity.     

The case for a “productivity norm”: Comment on Dowd

Instead of aiming for zero inflation, a “productivity norm” would allow permanent changes in the price level reflecting opposite changes in productivity or unit costs of production. Dowd (1995) disputes my claim that a productivity norm would be more conducive to macroeconomic stability than a stable price level. But Dowd's arguments succeed in undermining the case for a productivity norm only to the extent that they also undermine his own case for zero inflation.
