The public acceptability of a policy is an important issue in democracies, in particular for anti-COVID-19 policies, which require the adherence of the population to be applicable and efficient. Discrete choice experiment (DCE) can help elicit preference ranking among various policies for the whole population and subgroups. Using a representative s...

We test the effectiveness of a social comparison nudge (SCN) to enhance lockdown compliance during the COVID-19 pandemic using a French representative sample ( N = 1,154). Respondents were randomly assigned to a favorable/unfavorable informational feedback (daily road traffic mobility patterns, in Normandy – a region of France) on peer lockdown com...

This study examines factors determining farmers’ investment in organic farming using a contextualized lab-in-the-field experiment with 220 small household farmers in Northern Vietnam. We focus on the role of network structure, information nudge, and social comparison between farmers using three types of networks: circle, star and complete. Our resu...

This study analyzes the spontaneous impact of human, social and natural capital on food crop technical efficiency (TE) in Sub-Saharan Africa (SSA). Our study contributes to the literature by adopting the meta-analysis method to investigate the relationship between TE and the three groups of capitals to better shed light on the TE in SSA regions. Ou...

Title: Les attendus d’une approche d’économie comportementale pour les décisions individuelles face à la pandémie de COVID-19 : succès et déceptions. Abstract: Dans le cadre du premier appel à projet « Flash-COVID-19 » de l’Agence nationale de la recherche, nous avons mobilisé des méthodes récentes de l’économie comportementale afin de mieux compre...

We study the effect of teacher subject knowledge on student achievement in mathematics and reading by using a data set from six sub-Saharan African countries. By using an estimation based on within-teacher within-student strategy, we can avoid a potential endogeneity bias. In most estimations and most countries, we do not find a significant teacher...

We test the effectiveness of a social comparison nudge to enhance lockdown compliance during the Covid-19 pandemic, using a French representative sample (N=1154). Respondents were randomly assigned to a favourable/unfavourable informational feedback (daily road traffic mobility patterns, in Normandy - a region of France) on peer lockdown compliance...

This paper analyzes a model of aid allocation equalizing the opportunity between recipient countries to reach a common poverty reduction goal. We propose a fair and efficient aid allocation based on a multicriteria principle. The model considers structural handicaps in recipient countries in terms of lack of human capital and economic vulnerability...

Based on a meta-analysis, this paper highlights the strength and relevance of several social incentive factors concerning pro-environmental behaviors, including social influence, network factors (like network size, network connection and leadership), trust in others, and trust in institutions. Firstly, our results suggest that social influence is n...

Extension services have become the gold standard for agricultural development programs to spur farm productivity and enhance farmers’ livelihood. Scholars from distinct strands of research have contested the virtues of these programs as systematic reviews failed to disentangle the different causal paths. We aim to unpack the relationship between th...

It is nowadays accepted that labour market institutions matter in economic development. However, empirical studies on unions’ effect are not univocal. We provide new insight into the impact of unions on the long-run performance of industrialized economies using an indicator of union centralization. Relying on a recent panel dataset of OECD countrie...

Existing studies disjointly addressed the environmental convergence and environmental Kuznets curve hypotheses, though these research lines are theoretically interconnected. This paper proposes a unified empirical methodology to simultaneously investigate both hypotheses, relying on a semiparametric dynamic panel data model that accounts for regres...

This paper experimentally investigates the impact of different information sharing mechanisms in a common-pool resource game, with a view to finding a mechanism that is both efficient and inexpensive for the managing agency. More precisely, we compare the observed extraction levels produced as a result of three mechanisms: a mandatory information s...

Do institutional and geographical characteristics matter for energy consumption similar to the case of economic development? Why do coastal Sub-Saharan African (SSA) countries appear to be more energy-consuming than inland ones? To answer these questions, surprisingly rarely addressed in the existing literature, we empirically assess the determinan...

Instructions of the experiment of article "Contrasting effects of information sharing on common-pool resource extraction behavior: experimental findings".

The ongoing ecological crisis has motivated systematic studies on biodiversity loss, mostly pointing to economic and human population pressure as root causes of natural habitat destruction. The present paper proposes to globally assess the case of threatened animal and plant species, discussing whether the cohabitation between human habitat and bio...

We first consider the question of the productivity of the economy of Vietnam at the macro level. With theoretical models and empirical data, we find out the Leontief production function, and its associated TFP (Total Factor Productivity). We show that the TFP is one of the main engines of Vietnam economic growth. However when we move to the micro l...

Cette note analyse l'architecture de la politique de cohésion de l'Union européenne (UE) et son impact sur la croissance économique des États bénéficiaires. À travers un état des lieux sur l'efficacité conditionnelle des Fonds européens structurels et d'investissement (FESI), cette note vise à enrichir le débat sur le budget européen de la période...

Increasing consumer awareness on sustainable and healthy food choices gave rise to a growing demand for organic tea in the past decades. Most of this demand is met by imports from developing countries. This article examines the main factors affecting the choice of farm households to adopt organic tea production in Northern Vietnam. We apply a logit...

This paper intends to determine an optimal allocation of the European Cohesion Fund (ECF) and compares it with the observed allocation. This optimal allocation is the solution of a donor optimization problem which maximizes recipient countries' GDP per capita to achieve economic convergence in the EU. Compared to the observed allocation, our soluti...

The impact of economic activity on the environment is considered an external effect when it is not taken into account in the decision‐making process of economic agents. This chapter introduces the general functioning of traditional forms of environmental regulation with examples of application. It discusses the main sources of ineffectiveness of th...

This paper analyzes the determinants of the households’ welfare perception using the data from surveys on rural households in Thailand and Vietnam. Welfare perception corresponds to the households’ subjective assessment of their general situations. We focus on the social comparison and take into account relative poverty, harsh living conditions, ec...

This paper analyzes the relationship between government expenditure, tax on returns to assets, public debt, and growth in an endogenous growth model. Public debt is composed of two components, domestic debt and external debt. We show conditions for existence, uniqueness, and multiplicity of the steady states. More precisely, existence of steady sta...

We propose a structural approach to investigate total factor productivity (TFP) and economic growth of 58 provinces and municipalities of Vietnam (known as one of the most dynamic emerging economies in the last few years). The analysis is applied to the provincial data that are available to us for the period 2000–2007. TFP is composed of three comp...

This article analyzes households’ choice on tea varieties in Vietnam by using a multinomial logit model. The modeling takes into account the issue of unobserved individual heterogeneity and the endogeneity of some explanatory variables (use of chemical and organic fertilizers). The results show that important factors influencing the decision to ado...

This paper examines the relationship between per capita energy consumption and per capita income and the determinants of this relationship using a panel data sample of 29 Sub-Saharan African countries over the period from 1980 to 2011. We explicitly account for country heterogeneity by using a panel data heterogeneous coefficients model. The findin...

The objective of this paper is to apply the stochastic production frontier methodology to a survey database collected in northern Vietnam. Our study finds that the average technical efficiency of tea production is only about 41 %. Among extension policy measures available to farmers, only training on production inputs has an improving impact on tec...

We rely on the methodology of Fischbacher et al. (Econ Lett 71(3):397–404, 2001) in order to identify subjects’ behavioral types. We then link the likelihood to act as a leader in a repeated public goods game to the elicited behavioral types. The leader in a group is defined as the subject who voluntarily decides in the first place about his contri...

This paper considers an optimal endogenous growth model where the production function is assumed to exhibit increasing returns to scale and two types of resource (renewable and nonrenewable) are imperfect substitutes. Natural resources, labor, and physical capital are used in the final goods sector and in the accumulation of knowledge. Based on res...

This paper provides a unified framework to investigate simultaneously environmental convergence and the environmental Kuznets curve hypothesis, which were usually separately investigated in existing literature. We propose an application on CO2 emissions data consisting of 106 countries observed over the period 1970-2010. We adopt an instrumental se...

This paper analyzes the determinants of international trade of wood products, considering three main groups: woodworking products, pulp and paper and wooden furniture. We extend the Heckscher-Ohlin-Vanek (HOV) framework in order to take into account the forest resource endowment as well as industrial performance factors. Empirical tests are based o...

Organizational innovation favours technological innovation. Yet the question of which organizational practices should be combined—that is, their compatibility—remains unanswered. This empirical investigation of patterns of complementarity considers three organizational practices: business practices, workplace organization and external relations. Fi...

Deregulation of the labour market and public budget balance are usually considered a fundamental requirement for economic performance. This study analyses the long term relationship between these indicators and gross value added (GVA) for a panel of European regions from 1995 to 2008. Following Olley and Pakes (1996), Levinsohn and Petrin (2003) an...

We empirically investigate the pattern of complementarity among four organizational practices. Firm-level data were drawn from the Community Innovation Survey, carried out in Luxembourg. Supermodularity tests confirm the crucial role of organizational innovation in raising firms’ technological innovation. The pattern of complementarity across organ...

Energy and capital are assumed to be complementary in the production process. New machines are less energy consuming and scrapping is endoge...

We compare the experimental results of three stag-hunt games. In contrast to Battalio et al. (Econometrica 69:749–764, 2001), our design keeps the riskiness ratio of the two strategies at a constant level as the optimization premium is increased. We define the riskiness ratio as the relative payoff range of the two strategies. We find that decreasi...

This paper analyzes endogenous ï¬scal policy and public decision in an endogenous growth model where agents care about social status and environmental quality. The quest for a higher status is assimilated to a preference for capital wealth. The government uses income tax to ï¬nance infrastructure and environmental protection, and maximizes individu...

We provide a reappraisal of income convergence across European regions over the last two decades by using a semiparametric partially linear model to approximate the relationship between the average growth rate of GDP per capita and the initial GDP per capita. Estimation results point out both country heterogeneity and non-linearity in the convergen...

The views and interpretations expressed in the paper are those of the author(s) and do not necessarily represent the views and policies of the DEPOCEN or its Management Board. The DE...

Organizational innovation has been shown to be favourable for technological innovation. However, the question of which organizational practices should be combined ? and thus of their compatibility ? remains unanswered. We here empirically investigate the complementarities between different organizational practices (business practices, knowledge man...

This paper proposes a semiparametric analysis for the study of the relationship between energy consumption per capita and income per capita for an international panel dataset. It shows little evidence for the existence of an environmental Kuznets curve for energy consumption. Energy consumption increases with income for a majority of countries and...

We provide a reappraisal of income convergence across European regions over the period 1990-2005 by using a semiparametric partially linear model to approximate the relationship between the average growth rate of GDP per capita and the initial GDP per capita. Estimation results point out both country heterogeneity and non-linearity in the convergen...

We experimentally investigate cooperative behavior in a social dilemma situation, where the socially efficient outcome may be encouraged by risk aversion and/or inequality aversion. The first part of our experiment is devoted to the elicitation of subjects' aversion profile, taking care to not confuse the two dimensions. Subjects are then grouped b...

Relying on a structural nonparametric estimation, we show that CO2 emissions clearly increase with income at low income levels. For higher income levels, we observe a decreasing relationship, though not significant. We also find that CO2 emissions monotonically increases with energy use at a decreasing rate.

We compare the experimental results of three stag-hunt games. In contrast to Battalio et al. (2001), our design keeps the riskiness ratio of the payoff-dominant and the risk-dominant strategies at a constant level as the optimisation premium is increased. We define the riskiness ratio as the relative payoff range of the two strategies. We find that...

This paper analyzes the transitional dynamics in a model of economic growth with endogenous technological change and two alternative sources of energy: renewable and non-renewable resources. The conditions for the existence and saddle point property of the steady state are given. Finally, we present the estimation results on the data consisting of...

We develop a general equilibrium vintage capital model with embodied energy-saving technological progress and an explicit energy market to study the impact of investment subsidies on investment and output. Energy and capital are assumed to be complementary in the production process. New machines are less energy consuming and scrapping is endogenous...

This paper proposes a semiparametric analysis for the study of the relationship between energy consumption per capita and income per capita for an international panel data. It shows little evidence for the existence of an environmental Kuznets curve for energy consumption. Energy consumption increases with income at an increasing rate for low incom...

Nous comparons les résultats expérimentaux de trois jeux de coordination de type "chasse au cerf" (stag-hunt). Contrairement à Battalio et al. (2001), notre protocole permet de maintenir constant le rapport des risques des risques des deux stratégies lorsqu'on augmente la prime d'optimisation. De plus, ce protocole permet de tester l'effect d'une d...

We use a panel data set of 59 developing countries over the 1972–1994 period to study the deforestation process. Relying on both parametric and semiparametric models, we examine nonlinearities and heterogeneity in the deforestation process. We first study the existence of an Environmental Kuznets Curve (EKC) and then analyze determinants of defores...

Nous utilisons un modèle semi-paramétrique partiellement linéaire pour étudier la convergence des régions européennes. Les données proviennent de la base Eurostat et portent sur 223 régions de l'Union européenne pour la période 1990-2000. Les concepts de /beta/-convergence (conditionnelle et inconditionnelle) et /sigma/-convergence sont examinés. L...

We use a partly linear semi-parametric model to study the convergence of European Union regions. The data are taken from the Eurostat base and cover 223 EU regions for the period 1990-2000. The estimation results indicate the presence of non-linearity and heterogeneity in the convergence process. Convergence occurs only in regions with low GDP per...

We compare the experimental results of three stag-hunt games. In contrast to Battalio et al.(2001), our design keeps the relative riskiness of the two strategies at a constant level as the optimisation premium is increased. Furthermore, we also test the effect of a decrease of the relative riskiness of the two strategies, when the optimization prem...

We use two datasets to study the convergence process across European regions. Relying on Quah (1966a,1997), we examine the dynamics of income distribution and find evidence of polarization whatever the time horizon considered. Regions whose incomes were close together at an initial period transit subsequently to widely different income levels.

We examine the empirical relation between CO2 emissions per capita and GDP per capita during the period 1960–1996, using a panel of 100 countries. Relying on the nonparametric poolability test of Baltagi et al. [Baltagi, B.H., Hidalgo, J., Li, Q., 1996. A nonparametric test for poolability using panel data, Journal of Econometrics 75, 345–367], we...

This paper uses nonparametric methods to examine the convergence in CO2 emissions per capita on a sample of 100 countries for the period 1966–1996. Industrial countries show a convergence pattern. However, there is little evidence of convergence for the whole sample.

We examine the empirical relation between CO2 emissions per capita and GDP per capita during the period 1960-1996, using a panel of 100 countries. Relying on the nonparametric poolability test of Baltagi et al. (1996), we find evidence of structural stability of the relationship. We then specify a nonparametric panel data model with country-specifi...

Melnik et al. [Melnik, A., Shy, Oz, Stenbacka, R., 2008. Assessing market dominance. Journal of Economic Behavior and Organization 68, 63-72] have proposed a new statistic to assess market dominance. In this comment we expand their discussion of certain mathematical properties in their analysis and link their methodology to some previous approaches...

We analyze the performance of firms from the German business-related service sector for 1994-2000. Performance is measured by ordinal assessment of changes in total sales. We estimate first-order Markov chain models using extensions of the multinomial logit model: a linear index model with alternative specifications of heterogeneity and a semiparam...

We compare a seven period repeated investment game to the one-shot investment game. On an average, in the repeated game, player A (the “trustor”) sends more and player B (the “trustee”) returns a larger percentage than in the one-shot game. Both the amount sent and the percentage returned increase up to period 5 and drop sharply thereafter. The “re...

We use a new extensive dataset to examine the convergence process across European regions. We propose a semiparametric partially linear model to approximate the relation between the average growth rate of GDP per capita and the initial GDP per capita. Estimation results show non-linearity and heterogeneity in the convergence process. Convergence em...
