VERTICAL DIFFERENTIATION AND THE DISTRIBUTION OF INCOME

The paper analyses the effects of income concentration on the behaviour of a duopoly with vertical product differentiation and uncovered market. By using a trapezoid distribution, we solve explicitly for market equilibrium as a function of a mean preserving spread of the income distribution. We show that overall more concentrated incomes imply stronger product differentiation, as the presence of a large share of middle‐income consumers stimulates a price competition, whose effects are dampened through an enlargement of the quality spread. While the high‐quality advantage and market coverage increase unambiguously in the degree of income concentration, the behaviour of prices is non‐monotone in the distribution parameter.

Exploring the Structure of the Illegal Market for Cannabis

Summary This paper explores the middle and retail levels of the illegal market for cannabis in New Zealand using national household drug survey data. Those who reported purchasing half or full ounces of cannabis were defined as middle level market participants, while those who purchased smaller weights or merely used cannabis were defined as retail level participants. Those who had purchased cannabis were then further categorised as either cannabis ‘buyers’ (i.e. those who only purchased sufficient cannabis for their own consumption needs) or cannabis ‘dealers’ based on whether the surplus of cannabis they had, after their own personal consumption was deducted, exceeded the legal definition of cannabis dealing (i.e. possession of 28 g of cannabis or more). Nine per cent of those who had purchased cannabis in the previous year were categorised as middle level participants with 69% of these defined as middle level dealers and 31% as middle level buyers. Middle level cannabis dealers were projected to earn, on average, $2927 (NZD) net annual profit from selling surplus (rate of return of 34%). There was a wide variation in the projected net earnings of the middle level cannabis dealers with the majority earning only modest incomes (bottom 50% – $260 per year, top 10% – $25000 per year). Participants at all levels of the market commonly reported receiving cannabis for ‘free’ and this is likely to reflect the social sharing of cannabis during group consumption and non-cash payments for cannabis. This barter and gift giving tradition may provide cannabis users with a degree of insulation from any price increases for cannabis brought about by law enforcement activity. Cannabis selling creates a convenient source of income for heavy cannabis users to finance their own personal cannabis consumption, which may also dampen the impact of any rise in price brought about by law enforcement success.The 2003 HBS-Drug Use was funded by the New Zealand Ministry of Health and carried out as part of the Public Health Intelligence (PHI) Health Behaviours Survey Monitor. The statistical design for the 2003 survey was completed by Dr. Megan Pledger at SHORE, and by James L. Reilly from Statistical-Insights. The questionnaire was adapted and extended from the National Drug Survey questionnaire for the Health Behaviours programme by Dr. Chris Wilkins. Data collection was managed by Dr. Chris Wilkins, Rachael Lane, Joe Morley and Mary Blade. The statistical analysis of 2003 HBS-Drug Use was completed by Paul Sweetsur. The analysis in this paper was partly funded by the New Zealand Police.     

REFRIGERATION AND DISTRIBUTION: NEW ZEALAND LAND PRICES AND REAL WAGES 1873–1939

The responses in New Zealand to the opportunities of refrigeration transformed farming in the Dominion during the half-century from 1890. Closer settlement and the extension of the cultivated area combined with more intensive farming methods to increase land productivity and real gross domestic product capita to the extent that living standards in New Zealand measured by the Human Development Index ranked first in the world by 1913. In contrast, real wages in the Dominion stagnated. The refrigeration-related trade boom had powerful income distribution effects that increased sharply the land rental–wage ratio during the years to 1920. Widely diffuse land ownership in New Zealand tempered the rise in income inequality, to set the Dominion apart from other land-abundant economies of the periphery.

Does market misvaluation help explain share market long‐run underperformance following a seasoned equity issue?

We examine the relation between pre‐seasoned equity offering (SEO) announcement date misvaluation and long‐run post‐SEO performance for a large sample of Australian SEOs made between 1993 and 2001. Our study is motivated by inconsistent findings across countries with respect to the SEO long‐run underperformance anomaly first documented in the USA, inconclusive findings with respect to the hypothesis that managers exploit market misvaluation when timing equity issues, and a recent Australian Stock Exchange proposal to loosen SEO regulation. We find SEO firms underperform common share market benchmarks for up to 5 years after the announcement. Using a residual income valuation method, we show that this underperformance is related to pre‐announcement date misvaluation. An unexpected result is that underperformance and misvaluation are more severe for private placements than rights issues. Institutional factors unique to the Australian setting, particularly the large number of smaller loss‐making firms among private placement issuers, appear to explain the poorer performance of placement firms. Our results are robust to various measurement methods and assumptions, and demonstrate the importance of researching SEO performance in alternative institutional settings.     

Immiserizing Growth in a Closed Economy

We develop a model with three key features: a factor market distortion, monopoly power in the product market and indivisibilities in consumption. In this setting, multiple equilibria arise, one with high and the other with low equilibrium wages, incomes and output. It is also shown that even in a closed economy, growth may be immiserizing and, finally, that redistribution could be a “rich man's game”.
