ESTIMATES OF THE VALUE OF HOUSEHOLD WORK CANADA, 1961 and 1971*

The paper presents some estimates of the imputed dollar value of household work (HW)for Canada in 1961 and 1971, finding this to be about $16 and $38 billion respectively, equal to 40 percent of GNP. From the results we derive some implications about five questions raised in the relevant literature. First, no clear evidence of a downward trend for the ratio HW/GNP is found, contrary to U.S. results. Second, addition of HW to GNP as a welfare measure does not affect the general pattern of past growth estimates. Third, a cost–by-function method of estimating HW is found superior in its theoretical support and the detail it provides, but the opportunity-cost method, despite doubts on its theoretical validity, gives a good approximation in the aggregate, and, being simpler, is likely to remain popular. Fourth, disaggregation does matter if detail by region or family type is required, in which case data by number and ages of children and market-employment status of females are needed; for the total, a reasonable estimate (6–7 percent error)is given by further aggregated data. Fifth, sensitivity of HW to accuracy in the data used is large only for female wages chosen, in particular for the function “cooking”. Finally, though available data must be manipulated to fit the needs of HW, especially for earlier years, the extent of this is not all that much more than is commonly found for GNP estimations.

Transition economies and trust building: a network perspective on EU enlargement

Many transition economies are characterised by a relativelyrudimentary institutional framework. Weak legislative structuresand the absence of effective market regulation and propertyright enforcement rules diminish the chance of mutually profitablebusiness transactions and—more generally—restrictthe chances for innovation and sustainable growth. Against thisbackground, we analyse the extent to which more efficient governancemechanisms can contribute to a more favourable business environment.In doing so, we adopt a network perspective. We argue that bothin developed market economies as well as in centrally plannedeconomies much of economic exchange takes place in networks.However, the characteristics of these networks, in particularthe concept of trust, can differ significantly. This leads usto conclude that the real challenge of the process of economictransition is connected to building new economic exchange networks.In this paper, we discuss this argument and analyse how thecurrent enlargement of the EU into Eastern Europe may favourablyaffect this process of institutional change in the accessioncountries.     

Trades outside the quotes: Reporting delay,trading option,or trade size?

In the period 1993 through 2002 examined in this study, quoted and effective spreads declined substantially on Nasdaq and to a lesser degree on the NYSE. At the same time, however, trades outside the quotes increased dramatically on Nasdaq. Because investors would prefer to trade at the quotes rather than outside the quotes, we examine why trades outside the quotes are observed. We focus on how the continuous market mechanism itself influences the outcome of orders and the reporting of trades, and we conclude that slippage exists in the market mechanism. Outside-trades occur on Nasdaq, first, because of delays in reporting trades, second, because the ability of dealers to delay execution of trades creates a look-back option, which when exercised results in outside-trades, and third, because large trades can take place at prices outside the quotes. Outside-trades are rarely observed on the NYSE because the market is more centralized. While the pattern of trading on the NYSE is not inconsistent with the presence of a look-back option, our tests provide no direct evidence that specialists are exercising such an option.     

Can neoclassical economics become social economics?

This essay has both a general and a specific purpose. Its general purpose is to pose the question: Can neoclassical economics be social economics? Its answer to this general question is: Yes, but only if it abandons its methodological soul; that is, by abandoning methodological individualism, positivism, and ahistoricism, and expressly and systematically adopting a methodological perspective which is holistic, normative, and historical. Its specific purpose is to identify and examine the major elements in the economics of one leading figure in the historical development of neoclassical economics who self-consciously attempted to combine, to paraphrase Schumpeter, a neoclassical head with a social economics heart: Alfred Marshall.

Contract equilibria in housing markets

The paper provides a contractual equilibrium model of differentiated housing markets. Within a competitive framework the existence of a contract equilibrium, respecting certain enforceability conditions, is shown. The allocation, induced by these contract equilibria in the housing markets, is possibly characterized by demand rationing, even under the assumption of free contract markets.
