Is There a Winning Formula for Union Organizing?

Between 1995 and 2004, Kate Bronfenbrenner wrote several studies arguing that union organizing would be more successful if certain tactics were used. Bronfenbrenner’s methodology seemed unassailable and her opinions were influential among union leaders, but organizing outcomes did not improve. To understand why, this study asked highly successful union organizers for their views. Their responses point to an entirely different conceptualization of the organizing process. Rather than follow a certain recipe, respondents saw their first priority as building relationships of trust with workers. Then, organizers and workers together could develop tactics tailored to the particular situation. If organizing success most requires relation-building skills and creativity, then it is more important for unions to hire the right organizers than to employ a given tactical formula.     

Is it a Timing or a Probability Effect? Four Simulations and an Application of Transition Rate Models to the Analysis of Unemployment Exit

Among the applications of event history analysis, in the last 10 years the lion's share has been played by proportional transition rate model. This type of models suffers from a major draw-back: it does not allow us to distinguish whether a covariate affects the event timing (the event occurs sooner/later) or the overall probability of the ultimate event occurrence (the chances of occurrence are constantly higher/lower). Thus, a positive/negative effect of a covariate found using a proportional transition rate model might reflect an acceleration/deceleration in the timing of the event and/or a high/low probability of the ultimate event occurrence (Yamaguchi, 1992). This paper shows how this problem can be reformulated in terms of the proportionality/non proportionality of the covariate effects. A twofold solution to disentangle the timing/probability problem is presented: this solution consists of a test of the proportionality of the covariate effects and a computation of the survival function at the end of the time interval studied. Two applications are discussed. The first one is based on four simulated processes. The second is based on an analysis of unemployment exit in Italy, with particular attention being paid to the effects of unemployment benefits. In the conclusion, implications for future applications of event history analysis are discussed.     

Challenging The Spirit Level: Is There Really a Relationship between Inequality and Obesity?

This paper examines the proposition, set out in The Spirit Level, that inequality is associated with high levels of obesity. It reviews existing literature and uses British Household Panel Survey data to study how district‐level and regional‐level income inequality is related to obesity in the UK. This is likely to be the first study of its type that uses individual‐level data that is representative of the UK population. We find little evidence to support policies that reduce income inequality with the aim of reducing obesity levels in the UK.     

Is entrepreneurship a virtue?

Entrepreneurship is rarely (if ever) discussed by virtue ethicists. And economists analysing entrepreneurship have rarely described it as a virtue. Entrepreneurship is indeed a virtue and the entrepreneur can be seen as the creative counterpart of Aristotle's ‘Magnificent Man’, the virtuous possessor of wealth. But entrepreneurship is also a virtue for anyone who is economically active. By reviewing analyses of entrepreneurship by economists such as Cantillon, Schumpeter, Knight, Baumol, Kirzner and Casson, particular features of entrepreneurial practice are identified from which characteristic virtues (and vices) are isolated and analysed. The characteristic features of the vicious Entrepreneur (or crooked businessman) are also described.     

Is the government in danger of inflating a housing bubble?

Despite very strong inflation prior to the financial crisis, the correction in UK house prices has been relatively modest and much smaller than those in countries such as the US, Ireland and Spain. The relative resilience of the UK market appears to be a reflection of very tight supply which has effectively put a floor under prices.…     

Is a co-jump in prices a sparse jump?

Systematic co-jumps in asset prices are generally thought to account for only a small proportion of overall jumps. In actual observations, however, jumps in asset prices are often persistent, and the time of persistence varies. In this context, we develop a new rule to identify co-jumps and improve traditional tests by considering different sampling frequencies and different sampling starting points to re-evaluate the occurrence rate of systematic co-jumps in financial assets. We conduct a simulation experiment to show that the current test procedures generally underestimate the number of co-jumps when considering persistence, but that the proposed procedure can identify co-jumps more accurately. We also perform an empirical analysis using price data from the Shanghai 50 Index and its 25 constituent stocks in China’s stock market. The average proportion of systematic co-jumps detected by the improved s-BNS is approximately 30%, which shows that the co-jump and even the systematic co-jump are not sparse jumps. The results also reveal the shortcomings of traditional jump tests in estimating persistent jumps and demonstrate that the proposed method can better detect the possible nondiversifiable risks between market indices and their constituent stocks, thereby contributing to financial risk management.     

Public versus private provision of liquidity: Is there a trade-off?

To what extent is public debt private liquidity? Much policy advice given in the aftermath of the financial crisis rests on the assumption that increasing public debt relaxes borrowing constraints of private households. This is the case for ad-hoc debt limits, which are exogenous to public policy. Instead, if debt limits are fully endogenous, as e.g. in the case of the natural borrowing limit, public debt has no impact. We assume that borrowing limits arise because of limited contract enforceability and are therefore determined as equilibrium outcomes. Using an incomplete markets economy in which households are subject to uninsurable earnings shocks, we show that public debt provides some liquidity, but less so than it would if constraints were imposed ad-hoc. We show that generating borrowing constraints as an equilibrium outcome substantially alters the answers to other important questions, such as for the welfare effects of government debt or its impact on real economic activity.     

Is the Stock Exchange a Casino?

'Primary investment' is the permanent addition to productive capacity which follows abstinence or saving. It is risky but the effects of uncertainty operate around the risk-free interest rate, not around an average of nil or worse as in a slot machine. Investment, as opposed to gambling, implies that the investor 'does his homework.' Gambling via the stock exchange has increased, especially because of the expanding role of institutional investors as agents for savers.     

Is having a unique equilibrium robust?

We investigate whether having a unique equilibrium (or a given number of equilibria) is robust to perturbation of the payoffs, both for Nash equilibrium and correlated equilibrium. We show that the set of n  -player finite games with a unique correlated equilibrium is open, while this is not true of Nash equilibrium for n>2$n>2$. The crucial lemma is that a unique correlated equilibrium is a quasi-strict Nash equilibrium. Related results are studied. For instance, we show that generic two-person zero-sum games have a unique correlated equilibrium and that, while the set of symmetric bimatrix games with a unique symmetric Nash equilibrium is not open, the set of symmetric bimatrix games with a unique and quasi-strict symmetric Nash equilibrium is.     

Is There Catch‐Up Growth? Evidence from Three Continents

The ability to correct deficiencies in early childhood malnutrition, what is known as catch‐up growth, has widespread consequences for economic and social development. While clinical evidence of catch‐up has been observed, less clear is the ability to correct for chronic malnutrition found in impoverished environments in the absence of extensive and focused interventions. This paper investigates whether nutritional status at early age affects nutritional status a few years later among children, using panel data from China, South Africa and Nicaragua. The key research question is the extent to which state dependence in linear growth exists among young children, and what family and community level factors mediate state dependency. The answer to this question is crucial for public policy due to the long‐term economic consequences of poor childhood nutrition. Results show strong but not perfect persistence in nutritional status across all countries, indicating that catch‐up growth is possible though unobserved household behaviours tend to worsen the possibility of catch‐up growth. Public policy that can influence these behaviours, especially when children are under 24 months old, can significantly alter nutrition outcomes in South Africa and Nicaragua.     

Is It Time to Revisit the Savings Rate Floor in the ECCU?

Member states of the Eastern Caribbean Currency Union (ECCU) experienced a secular decline in growth following the great recession circa 2008, resulting in increased unemployment and social dislocation. Given the ECCU's currency board arrangement and current fiscal challenges, policy options for resuscitating growth are limited to supply‐side adjustments. This paper contends that the 3 per cent interest rate floor on savings deposits has contributed to higher lending rates and lower levels of capital formation. Ultimately it is a drag on growth and a threat to the banking sector's health as it has resulted in reduced risk compensation when default and other banking sector risks have risen. Revisiting the floor is advocated as an integral component of this structural adjustment policy response.     

Is There Any Ethical and Moral Consideration in the Theory and Practice of Global Business Social Darwinism?

Abstract

This article has revisited the interchangeable meanings of morality and ethics in today's global business practices. This article argues that in the theory and practice of the global business Social Darwinism, there is no room for ethics and morality because the competitive international business ideology promotes the “survival of the fittest.” Furthermore, the purpose of this article is to first define the distinction between morality and ethics and their application in the real world of today's business; second, to analyze the ideological foundation of the international business practices of Social Darwinism in relation to global production, consumption, profitability, and efficacy.     

Scarce or Abundant? The Economics of Natural Resource Availability

Most natural resources that are used in production are non‐renewable. When they become depleted they are lost for future use. Does it follow that the limited availability of natural resources will at some time in the future constrain economic growth as many environmentalists believe? While classical economists have shared the belief in limits to growth, the distinctive feature of modern neoclassical economics is its optimism about the availability of natural resources. This survey suggests that resource optimism can be summarised in four propositions. First, a rise in the price of a resource leads to a substitution of this resource with another more abundant resource and to a substitution of products that are intensive in this resource. Second, a rise in the price of a resource leads to increased recycling of the resource and to the exploration and extraction of lower quality ores. Third, man‐made capital can substitute for natural resources. Fourth, technical progress increases the efficiency of resource use and makes extraction of lower quality ores economical. In a critical analysis of these four propositions it is shown that while the conjecture that natural resources will never constrain future economic growth is logically conceivable, we do not and indeed cannot know whether it will be possible in practice to overcome any resource constraint.
