The diary of a charity donor: an exploration of research information from the Royal Mail Consumer Panel and Mail Characteristics Survey

This paper looks at direct mail in the United Kingdom across all market sectors and in detail at the charity sector. It uses the research information that Royal Mail has been collecting foroveradecadetoshowthegrowthofthe medium. The diary system used by the Consumer Panel gives an insight into the typical donor and their relationship with charities. This paper looks only at direct mail: ‘personally addressed advertising material that is delivered through the post’. This definition means that leaflets put through the letterbox are excluded.

Sterling’s rise: A case of delayed overshooting?

In this article Francis Breedon discusses how sterling’s rise over the last 6 months can be explained in terms of a delayed overshooting reaction to past monetary policy. Although the timing is still hard to judge, it seems that this effect should now begin to wear off, allowing sterling to fall – particularly against the DM. As far as future monetary policy is concerned, this delayed overshoot is another argument for the Treasury and Bank of England undertaking a more activist exchange rate policy, perhaps following the example of another open economy on the fringes of EMU – Switzerland.     

Statistical Analysis of Choice Experiments and Surveys

Measures of households' past behavior, their expectations with respect to future events and contingencies, and their intentions with respect to future behavior are frequently collected using household surveys. These questions are conceptually difficult. Answering them requires elaborate cognitive and social processes, and often respondents report only their “best” guesses and/or estimates, using more or less sophisticated heuristics. A large body of literature in psychology and survey research shows that as a result, responses to such questions may be severely biased. In this paper, (1) we describe some of the problems that are typically encountered, (2) provide some empirical illustrations of these biases, and (3) develop a framework for conceptualizing survey response behavior and for integrating structural models of response behavior into the statistical analysis of the underlying economic behavior.     

Two Trees

We solve a model with two i.i.d. Lucas trees. Although the correspondingone-tree model produces a constant price-dividend ratio andi.i.d. returns, the two-tree model produces interesting asset-pricingdynamics. Investors want to rebalance their portfolios afterany change in value. Because the size of the trees is fixed,prices must adjust to offset this desire. As a result, expectedreturns, excess returns, and return volatility all vary throughtime. Returns display serial correlation and are predictablefrom price-dividend ratios. Return volatility differs from cash-flowvolatility, and return shocks can occur without news about cashflows.     

Explaining economic growth in the Soviet Union, 1950–86

Production function estimates are provided for Soviet industrial production and gross national product for the period 1950–86. A variety of alternative specifications is tested, including Cobb-Douglas, constant elasticity of substitution and variable elasticity of substitution production functions, and an error correction mechanism is used to investigate the long-run properties of the estimated equation. The structural stability of the estimates is also examined. Constant-returns-to-scale Cobb-Douglas production functions suggest that the rate of total factor productivity growth in the Soviet economy has declined steadily over time, becoming negative sometime in the period between 1970 and 1980. However the extensive statistical tests can doubt on the validity of any production function estimated on Soviet data.     

The Opening, Short, Medium and Long Term Performance of Canadian Unit Trust Initial Public Offerings (IPOs)

Abstract:   This paper investigates the initial pricing and performance of Canadian unit trust IPOs over a three‐ to four‐year period and then draws implications for the efficiency of the Canadian market. Overall, the results confirm the following: in the short term, unit trust IPOs are underpriced and outperform the Canadian market; in the medium term, IPOs are fairly priced and neither outperform nor underperform the Canadian market; and in the long term, IPOs are fairly priced but underperform the Canadian market. In addition, our results confirm that the size of underpricing is related to ex‐ante uncertainty about the value of the issue. Ex‐ante uncertainty proxies, namely total risk, exchange listing, relative bid‐ask spread, and relative volume of initial trade, all explain the size of underpricing. When the effects of these factors are controlled, the results confirm that Canadian unit trust IPOs are indeed overpriced in the short term but underpriced in the long term. We conclude that the Canadian unit trust IPO market appears to be inefficient in the short and long term, but over the medium, the market appears to be efficient.     

A Cox Parametric Bootstrap Test of the von Liebig Hypotheses

This study uses a Cox parametric bootstrap test to select between two specifications of the von Liebig hypothesis, a switching regression (SR) model, and a linear response function with a stochastic plateau. Specifying the production function as a linear response function with a stochastic plateau yields a superior approximation of the data for livestock gain as a function of forage allowance than the SR approach.
Dans la présente étude, nous avons utilisé la technique du bootstrap paramétrique de Cox pour choisir entre deux caractéristiques de l'hypothèse de von Liebig: un modèle de régression avec changement de régime et une fonction de réponse linéaire avec plateau stochastique. établir la fonction de production comme une fonction de réponse linéaire avec plateau stochastique offre une meilleure approximation des données sur le gain de poids du bétail comme fonction de l'apport de fourrages comparativement au modèle de régression avec changement de régime.
