Are false own-account workers less job satisfied than true ones?

This article compares job satisfaction of true and false own-account workers. The latter group refers to own-account workers who are employed with the same tasks by the same employer for whom they previously worked as employees. To create a valid comparable group, the former workers are defined as paid employees who independently started a new business as own-account workers. Using data drawn from the European Community Household Panel for the EU-15 and controlling for possible self-selection issues, we observe that false own-account workers, compared with true ones, have less job satisfaction in terms of type of work, number of working hours, working times, and working conditions and environment. Our results are consistent with existing policies aimed to combat false self-employment developed by many OECD countries.     

Hidden costs of supply management in a small market

Canada regulates its dairy and poultry industries through supply management. The supply‐management programs use target prices, production quotas and import tariff‐rate quotas to raise domestic prices. Canadian supply‐managed producers cannot export their output to world markets as exports would be considered subsidized under World Trade Organization rules. In this paper, we show that once foregone export opportunities are accounted for, supply management may no longer be beneficial to domestic producers of the supply‐managed commodities. The extent to which foregone profits from exports dominate domestic rents depends on Canada's comparative advantage, domestic market elasticities and the extent of supply management distortion in the domestic market.     

Testing the martingale difference hypothesis in CO2 emission allowances

This study examines the martingale difference hypothesis (MDH) for the carbon emission allowance market within the European Union Emission Trading Scheme (EU ETS) during the Phase I and the Phase II, using both daily and weekly data over the 2005–2009 period. We analyze the MDH for spot prices negotiated on BlueNext, European Energy Exchange and Nord Pool along with futures prices negotiated on BlueNext and European Climate Exchange, using the new variance ratio tests developed by Kim (2009) and the generalized spectral test proposed by Escanciano and Velasco (2006). For the Phase I, the results show that the spot price changes of these three markets are predictable, suggesting the possibility of abnormal returns through speculation, except during the period April 2006 to October 2006, namely after the compliance break and before the ECs of stricter NAP II. Finally, we find that the CO₂ spot and futures price changes are unpredictable during the Phase II because we failed to reject the MDH based on both daily and weekly data. Thus, these markets are found to be weak-form efficient.     

Pulse Fishing and Stock Uncertainty

Large variation in stock dynamics affects the accuracy of stock estimates, which fisheries managers rely on when determining quotas and other regulations. The purpose of this paper is to investigate the implications of uncertainty on pulse fishing. We show that as the variance of the random natural fluctuations increases, the optimal pulse length decreases and converge toward a constant-escapement policy. Hence, in fisheries with large natural variability, a constant-escapement policy is a good approximation of the optimal policy.     

DOES THE MISSION OF PROVIDERS MATTER ON A QUASI‐MARKET? THE CASE OF THE BELGIAN ‘SERVICE VOUCHER’ SCHEME

ABSTRACT 1 : In 2001, the Belgian government introduced a ‘service voucher’ scheme in the field of domestic (housework) services, following a quasi‐market mechanism which fosters competition between providers of different types as regards sector (for‐profit, public, third sector) and mission (seeking profits, home care provision to vulnerable groups and work integration of the unemployed). Empirical evidence suggests that third sector organizations focusing on a social mission recognized by a tutelary regulation are the best performing with regards to the quality of jobs and service organization, leading to a better ‘triangulation’ of the service relationship. On the other hand, for‐profit providers, especially temporary work agencies, seem to favour their capacity of adaptation to the desiderata of their clients and costs’ minimization to the detriment of the quality of jobs which are made as flexible as possible.     

International trade,job training,and labor reallocation

A large literature studies the impact of increased import competition on workers' outcomes, however, relatively few studies examine which policies can aid workers displaced by trade. In this article, we evaluate the impact of an industrial job training program in Brazil on workers displaced from manufacturing sectors. We find that industrial training increases the probability of re-entry into the formal labor market 1 year after displacement by about 17 percentage points and is even more effective for workers displaced from sectors exposed to high import competition. This effect is mainly associated with workers switching sectors and occupations after training.     

Country Differences in Material Deprivation in Europe

This paper assesses to what extent differences in the characteristics of individuals (micro‐level perspective) and country‐specific factors (macro‐level perspective) can explain country differences with respect to material deprivation levels. Thus, our work aims to simultaneously consider the macro dimension and the predominantly individually‐oriented study field of material deprivation using multilevel techniques. We make use of the European Union Statistics on Income and Living Conditions. Our results show that country‐specific factors seem to be much more relevant than individual effects in explaining country differences in material deprivation. We estimate that the introduction of country‐specific factors reduces the proportion of total variance due to between‐country differences in deprivation by 72.7 percent, while individual‐level variables reduce this proportion by only 9.4 percent. We also show, through interaction variables, that the effect of sociodemographic characteristics can be shaped by institutional and structural factors, especially by the level of GDP.     

Inertia Risk: Improving Economic Models of Catastrophes*

We model endogenous catastrophic risk in a new way. We call it “inertia risk”, which accounts for delays between physical variables and the hazard rate – a characteristic often observed in reality. The added realism significantly affects optimal policies relative to the standard model of catastrophic risk. The probability of a catastrophe occurring at some point in time can span the entire interval [0,1], and is not 0 or 1 as is typical in standard models. Inertia risk can also generate path dependences. We illustrate the implications for policy in a simple model of climate change.     

What hinders innovation performance of services and manufacturing firms in Mexico?

Barriers to innovation are heterogeneous, of financial and non-financial nature. The importance of barriers to innovation and their actual influence on innovation depend on firms’ characteristics such as sectoral affiliation, technological behavior and their response to perceived obstacles to innovation. Firms either continue to engage in innovation, or they avoid the activity altogether. This paper explored the nature and perceived importance of the obstacles to innovation that firms confront, in a developing-country context; we build on survey data about firms in Mexico. Our findings suggest that two kinds of policy interventions should help offset a firm’s perception of barriers to innovation. On the one hand, policies should enhance the innovation capacity of firms interested in innovation; on the other hand, policies need to tackle factors that reduce the interest of firms in innovation. Policies that boost demand for locally generated innovations would assist in achieving both these goals.
