Gibrat’s law and legacy for non-profit organisations: a non-parametric analysis

Gibrat’s Law of proportional effect (i.e. growth is independent of initial size) has been tested for firms for several decades. In this paper I test Gibrat’s Law for charities in England and Wales through time. Using a data set based on the population of registered charities from 1998 to 2009, I am able to test the ‘ex ante’ hypothesis that Gibrat’s Law holds over the long run for a sample of charities as well as testing Gibrat’s Legacy (that Gibrat’s Law holds for large and mature organisations), the ‘ex post’ hypothesis. I use nonparametric local polynomial smoothing techniques which are more robust to the issues of autocorrelation, sample selection and truncation that make the conventional parametric approaches to testing Gibrat’s Law difficult in practice. Results suggest that the dynamic processes driving growth in the charitable sectors may differ from those driving the growth of firms. Unlike for-profit firms Gibrat’s Law is found to generally hold when controlling for selection both ‘ex ante’ and ‘ex post’. Results may be driven by the absence of a minimum efficient scale which charities must achieve to survive and the different funding profiles of charities

Unofficial Development Assistance: A Dynamic Model of Charities' Donation Income

The empirical literature on the determinants of charities donation income, distinguishing the charitable cause, is small. We extend the literature in several ways. First, we focus on overseas development charities allowing us to give more consideration to the particular characteristics of this cause. Second, we look at the impact of macroeconomic change over a quarter century including changes in household income and in government spending on ODA, as well as 'charity level' variables that earlier authors have considered. Third, we use a general dynamic model and rigorous testing procedures to arrive at our specification. Using a newly assembled long panel of data, we find evidence of a strong, but diminishing fundraising effect. We find no evidence of crowding out by either grants made directly to charities or by changes in the public provision of development funding.overseas development, charitable giving

Risk aversion and inequity aversion in demand for unemployment benefits

This paper is an empirical study of what motivates net contributors to support redistributive policies. While studies in the area have tended to consider broad measures of inequality and support for redistribution in general, we focus on a single, salient relationship between local unemployment rates and demand for spending on unemployment benefits. Using a particularity of the Spanish labour market, we estimate how workers' stated preferences for unemployment benefits spending respond to changes in the local unemployment rate. We then decompose this response into the part explained by risk aversion, and thus demand for insurance, and the part explained by inequity aversion. Our results suggest that increases in local unemployment rates lead to increased demand by workers for unemployment benefits spending. Moreover, our results are consistent with an insurance motive driving this relationship but provide little support for inequity aversion. Our results suggest that studies of the relationship between inequality and demand for redistribution might benefit from considering both the source and measure of the inequality and the instrument of redistribution

Is income redistribution a form of insurance, a public good or both?

This paper is an empirical study of redistributive preferences. Our interest is what motivates net contributors to support redistributive policies. Using instrumental variable estimation and exploiting a particularity of the Spanish labour market we estimate how workers’ declared preferences for unemployment benefits spending respond to changes in the local unemployment rate. We then decompose this response into the part explained by risk aversion, and thus demand for insurance, and the part explained by the public goods nature of redistribution. Our results suggest that the declared preferences of workers for unemployment benefits spending are driven by demand for insurance rather than any public goods component. We show how these results suggest that preferences for redistribution in the form of unemployment benefits are driven by Insurance considerations rather than by any public goods consideration

Charitable bequests and wealth at death

Charitable bequests are a major source of income for charities but surprisingly little is known about them. The aim of this paper is to propose a multi-stage framework for analysing the bequest decision and to examine the evidence for Great Britain provided by new data on estates. The novelty of the framework is that it distinguishes between the different steps that lead to a charitable bequest. Our new data for Britain have the advantage of covering the whole population, in contrast to much of the US literature based on the small fraction of the population covered by estate tax returns. We focus on the relationship with wealth at death, on the form of the bequest, and on the different causes to which people bequeath

Charitable Giving for Overseas Development: UK trends over a quarter century

Charitable giving is an important source of funding for overseas development and emergency relief. Donations in the UK are about a quarter of the size of government development aid. There has been strong growth over time, reflecting the activities of development charities and the public response to humanitarian emergencies. The paper examines how this charitable giving has changed since 1978, using a newly constructed panel data set on donations to individual UK charities. When did the increase take place? Did the public respond to events such as Live Aid or has there been a steady upward trend? What has been the relationship with changes in household income? Which charities have grown fastest? Have new charities displaced old? How do changes in giving for overseas compare with changes in giving for other causes?charitable giving, overseas development

Charitable giving for overseas development: UK trends over a quarter century

Charitable giving for overseas development and emergency relief is important in the UK, being about a quarter of the size of government development aid. There has been a strong growth over time, reflecting the activities of development charities and the public response to a series of humanitarian emergencies. This paper examines how individual overseas giving has changed over the quarter century since 1978, using a newly constructed panel data set on donations to individual UK charities. When did the increase take place? Did the public respond to events such as Live Aid? Or has there been a steady upward trend as our society became more globalised? What form did the increase in giving take? Which charities have grown fastest? Have new charities displaced old? How do changes in giving for overseas compare with changes in giving for other causes such as cancer relief or animal welfare? What, if any, is the relation with Official Development Assistance

Off-axis effects on the multipulse structure of sperm whale usual clicks with implications for sound production

The definitive version was published in Journal of the Acoustical Society of America 118 (2005): 3337-3345, doi:10.1121/1.2082707.Sperm whales (Physeter macrocephalus) produce multipulsed clicks with their hypertrophied nasal complex. The currently accepted view of the sound generation process is based on the click structure measured directly in front of, or behind, the whale where regular interpulse intervals (IPIs) are found between successive pulses in the click. Most sperm whales, however, are recorded with the whale in an unknown orientation with respect to the hydrophone where the multipulse structure and the IPI do not conform to a regular pulse pattern. By combining far-field recordings of usual clicks with acoustic and orientation information measured by a tag on the clicking whale, we analyzed clicks from known aspects to the whale. We show that a geometric model based on the bent horn theory for sound production can explain the varying off-axis multipulse structure. Some of the sound energy that is reflected off the frontal sac radiates directly into the water creating an intermediate pulse p1/2 seen in off-axis recordings. The powerful p1 sonar pulse exits the front of the junk as predicted by the bent-horn model, showing that the junk of the sperm whale nasal complex is both anatomically and functionally homologous to the melon of smaller toothed whales.This work was funded by grants to from the Office of Naval Research Grant Nos.
