Economic Impact of 'Third-Wave' Cognitive Behavioral Therapies:A Systematic Review and Quality Assessment of Economic Evaluations in Randomized Contr…
2018
The term third-wave cognitive behavioral therapy (CBT) encompasses new forms of CBT that both extend and innovate within CBT. Most third-wave therapies have been subject to randomized controlled trials (RCTs) focused on clinical effectiveness; however, the number and quality of economic evaluations in these RCTs has been unknown and may be few. Evidence about efficiency of these therapies may help support decisions on efficient allocation of resources in health policies. The main aim of this study was to systematically review the economic impact of third-wave therapies in the treatment of patients with physical or mental conditions. We conducted a systematic literature search in PubMed, Psy…
Interventions with Sticky Social Norms: A Critique
2021
Abstract We study the consequences of policy interventions when social norms are endogenous but costly to change. In our environment, a group faces a negative externality that it partially mitigates through incentives in the form of punishments. In this setting, policy interventions can have unexpected consequences. The most striking is that when the cost of bargaining is high, introducing a Pigouvian tax can increase output—yet in doing so increase welfare. An observer who saw that an increase in a Pigouvian tax raised output might wrongly conclude that this harmed welfare and that a larger tax increase would also raise output. This counter-intuitive impact on output is demonstrated theore…
Free riding as méchanism
1998
Free-riding is methodologically puzzling. It is at the same time important and often not observed as an actual phenomenon. The paper explores the possibility of treating free riding as an underlying or causal mechanism. As such, free riding is to be treated as part of the real world rather than of the world of models or theories. However, the free riding mechanism is particularly prone to operate not in isolation but together with other mechanisms. This feature has consequences on issues such as empirical content, testability or relevance. These questions are discussed in the light of some recent work in philosophy of science and with special attention given to the development of experiment…
Verso la rappresentazione e valutazione dello sviluppo delle aziende : i limiti dell'informativa economico-finanziaria e il contributo di alcuni appr…
2009
Firms are dynamic entities in continuous change. This dynamism can lead to an improvement or worsening of the firm. Only in the first situation we can say that a firm is developing. The notion of firm's development does not have in literature an univocal interpretation and for this reason the first aim of the article is to illustrate an interpretation for a better understanding of this notion, which remains incomplete without appropriate instruments for the representation and evaluation of firm's development. The main purpose of this article is to reflect upon the manner to represent and to value this complex phenomenon. The analysis highlights, on the one hand, the limits of the financial …
Bicausative matrices to measure structural change: Are they a good tool?
1999
The causative-matrix method to analyze temporal change assumes that a matrix transforms one Markovian transition matrix into another by a left multiplication of the first matrix; the method is demand-driven when applied to input-output economics. An extension is presented without assuming the demand-driven or supply-driven hypothesis. Starting from two flow matrices X and Y, two diagonal matrices are searched, one premultiplying and the second postmultiplying X, to obtain a result the closer as possible to Y by least squares. The paper proves that the method is deceptive because the diagonal matrices are unidentified and the interpretation of results is unclear. Keywords : Input-Output ; Ch…
About the criteria of output coincidence for forecasts to determine the orientation of the economy (application for France, 1980-1997)
2000
This note indicates that the method of output coincidence for forecasts used to determine if sectors are demand-driven or supply-driven in an input-output framework mixes two effects, the structural effect (choosing between demand and supply driven models) and the effect of an exogenous factor (final demand or added-value). The note recalls that another method is possible, the comparison of the stability of technical and allocation coefficients, generalized by the biproportional filter: if for a sector, after biproportional filtering, column coefficients are more stable than row coefficients, then this sector is declared as not supply-driven (but one cannot decide that it is demand-driven a…
Coordination games with asymmetric payoffs: An experimental study with intra-group communication
2020
Abstract Two alternative modes of reasoning in coordination games are prominently discussed in the literature: level-k thinking and team reasoning. In order to differentiate between the two modes of reasoning, we experimentally investigate payoff-asymmetric coordination games using an intra-group communication design that incentivizes subjects to explain the reasoning behind their decisions. We find that the reasoning process is significantly different between games. In payoff-symmetric games, team reasoning plays an important role for coordination. In payoff-asymmetric games, level-k reasoning results in frequent miscoordination. Our study clearly illustrates how small differences between …
A global perspective on effectiveness of aid for trade
2013
Recent global initiatives on debt relief and development assistance call for increasing aid for trade to the poorest countries. The paper applies a multi-country computable general equilibrium model to measure the effectiveness of alternative aid for trade categories. The findings show that aid for trade policies expand trade and alleviate international income inequalities in the recipient countries, that will benefit mainly from aid for trade adjustment and technical assistance.
Controlled-by-owner firms, mobility of capital and microeconomic profit rate maximization
1999
When they actively control the firm, owners select the firm that has the best profit rate if the hypothesis of mobility of capital is adopted: controlled-by-owner firms are profit-rate-maximizing when sleeping-owner firms are pure-profit-maximizing. Both types are compared in monopoly, in perfect competition, in classical or in mixed duopoly. Always, controlled-by-owner firms have a lower output than comparable sleeping-owner firms. It only takes a fixed coefficient of equity capital to do that price plays no role for controlled-by-owner firms in perfect competition; in duopoly, it only takes a similar condition plus a linear demand to do that reaction functions vanish.
Estimation des modèles dynamiques à erreurs composées avec autocorrélation par la méthode des variables instrumentales
1996
In this paper, we consider a dynamic error-components models with autocorrelated disturbances. We analyse the efficient estimation procedure of autocorrelation parameter and we try to find out whether moment conditions of a dynamic model without autocorrelation are valid when the model includes autocorrelation. We propose two efficient estimation methods of autocorrelation parameter in addition to Baltagi and Li (1994) estimator. We show that all moment conditions of a dynamic model without autocorrelation are not valid in dynamics errors-components models with autocorrelated disturbances.
