are emotions to blame the impact of non analytical information processing on decision making and implications for fostering sustainability policy advice based on a rationalist perspective to foster sustainable behaviour has approached its limits and gaps in the established models are becoming more and more obvious to better understand how unsustainable choices are made and to foster sustainable decision making alternatives to the rationalist models of human decision making need to be investigated such alternative models have already demonstrated their usefulness in other fields than ecological economics the paper begins with a presentation of conventional models of human behaviour as well as their advances and limitations in ecological and behavioural economics in most of these models the dominance of analytical thinking still prevails i identify this as problematic given the evidence for the influence of emotion and intuition in decision making to offer a perspective on human behaviour that acknowledges this influence dual process models are presented established applications of these models are then used to propose four basic types of explanations for unsustainable behaviour based on these explanations preliminary ideas to promote sustainable decision making are developed these ideas are considerably different from policy implications of the established economic model

the starfish effect can market entry by one firm encourage further entry by others abstract this paper examines the impact of entry decisions into oligopolistic markets upon the entry and exit decisions of rival producers when learning economies are important entry by one firm may paradoxically make entry more attractive to others by weakening the ability of a dominant incumbent to produce at low cost the likelihood of this outcome depends upon the extent to which variable costs of production decline as output increases and is enhanced by scope economies in the presence of multi market contact as well as by the degree of cost asymmetry between firms it is suggested that entry inducing entry may actually have occurred in part of the market for large civilian passenger aircraft whether or not this is so a more general conclusion is robust in industries where scale and scope effects are large the impact of entry is not just upon competition but on costs and these effects work in opposite directions to influence the entry decisions of other firms

policy rivalry among industrial states what can we learn from models of strategic trade policy the economic theory of international trade has changed dramatically over the last decade by admitting into its mainstream a body of literature that focuses on the implications of monopolistic and oligopolistic elements in international markets by applying the tools of the new industrial organization in an international context two new classes of models have emerged models of intra industry trade and models of strategic trade policy the policy implications of models of strategic trade policy were quite disturbing for the economics profession since these models demonstrated that the classical harmony between national and cosmopolitan welfare maximization does not exist if one assumes opportunities for strategic manipulation of oligopolistic international industries this article reviews two prominent models of strategic trade policy the brander spencer model and the krugman model and relates them to more familiar earlier concepts such as stackelberg s asymmetrical duopoly solution and the venerable infant industry argument for government intervention the primary purpose of this article however is to provide a synopsis of the large literature addressing the question of whether models of strategic trade policy can give guidance for government policy

the impact of price floors on farmland investments a real options based experimental analysis price floors are a common instrument for market intervention to stimulate investments in some cases it can be observed that a price floor does not have the stimulating effect we experimentally analyse the investment behaviour of students who take the role of farmers the experiment considers an investment problem under uncertainty in a with price floor and a no price floor treatment stylizing a decision to take an ongoing farmland investment option we compare the actual investment behaviour with normative benchmarks of the net present value and the real options approach furthermore we look at order and learning effects the results show that the price floor has no significant impact on the willingness to invest whereas the effects of order were statistically significant the investment reluctance arising from an abolishment is stronger than the investment stimulation arising from the introduction of a price floor furthermore neither the net present value nor the real options approach is appr

endogenous market structures in international trade natura facit saltum abstract almost all of the large literature on international trade with imperfect competition assumes exogenous market structures the purpose of this paper is to develop a simple model that generates alternative market structures as nash equilibria for different parameterizations of the basic model equilibrium market structure is a function of the underlying technology familiar configurations such as a duopoly competing in exports or a single multinational producing in both markets arise as special cases small tax policy changes can produce large welfare effects as the equilibrium market structure shifts implying discontinuous jumps in prices quantities and profits

which factors influence the expansion of bioenergy an empirical study of the investment behaviours of german farmers the german government is planning to increase the share of renewable energy sources in this context it is important to understand the decision making behaviour of farmers regarding investments in renewable energy systems that generate energy from biomass and farmers reactions to investment support measures to study this behaviour we conduct a survey and confront farmers with a hypothetical opportunity to invest in a biogas plant our findings reveal that farmers have heterogeneous investment thresholds their investment decisions are mainly driven by capital costs and the subjective perception of the risk resulting from the investment other decision parameters like sustainability and non monetary objectives that are also examined in this paper play only minor roles however bounded rationality is an important factor moreover the influence of an investment subsidy was analysed only about half of the amount of the subsidy as expected according to normative forecast models is reflected in an increased willingness to invest furthermore farmers who have previously invested in bioenergy plants show lower investment thresholds and have stronger reactions to the subsidy regarding the expansion of renewable energies these findings are meaningful for policy impact analysis

persistent protection in an international exit game abstract this paper examines the strategic behavior of two countries in a duopoly exit game with declining demand in the export market we consider whether countries have a strategic rational to maintain rather than unilaterally or jointly reduce their subsidies conditions under which persistent subsidization is justified from a national perspective are derived by maintaining subsidies one country can gain a strategic advantage by forcing its rival to exit earlier an outcome where only one country applies the subsidy is not attainable free trade is less likely to occur close to the end of the game

regulation in the european community all governments regulate economic activity in their own countries the single european market will involve a significant transfer of regulatory activity from member states to the european community as well as the initiation of regulatory activity in certain areas that have not previously been subject to regulation at all including the activities of member states themselves as in taxation or the provision of subsidies to industry why should governments wish to make such a transfer of powers what do they have to gain

public provision of sales contingent claims backed finance to smes a policy alternative abstract in europe and elsewhere governments intervene to stimulate innovation in the sme sector and because smes face financial constraints in particular governments encourage the provision of debt and equity venture capital finance to such firms this paper discusses sales contingent claim scc backed finance funding secured only on a claim written on sales that offers a different repayment profile to debt and equity the attractiveness of such finance to firms as well as the behaviour of firms financed in this way are analysed for various reasons scc backed financial instruments are generally not available to smes on the market but it is argued that wider availability could further stimulate the growth and innovative activity of smes the correction of this market incompleteness by the introduction of government schemes providing scc backed corporate finance for smes in higher risk higher tech sectors is recommended the workability of such a scheme is explored by looking at existing examples aimed largely at project finance for larger firms

export subsidies as an outcome of the management labor conspiracy a mercantilistic trade policy is often introduced as a tool to generate more jobs in some key industries when employment in an export import industry is perceived to be low the government would be tempted to adopt measures of export promotion import protection to increase it by effectively guaranteeing employment however these policies would reduce incentives for the private sector to reach efficient labor contracts for example the labor union might refuse to sign a profit sharing contract with management and unilaterally demand high wages believing that the resulting loss in competitiveness would not affect the well being of its members since the government would protect the industry it is also conceivable that management and the labor union conspire to reach inefficient contracts so as to invite government intervention in certain cases trade policies only transfer income without any allocative effect this is not merely a theoretical curiosum free trade advocates have often pointed out that protectionist policies would have deleterious effects on the pattern of collective bargaining in the trade sensitive sectors this paper constructs simple models to illustrate this point for export subsidies and so it can be viewed as an addition to the literature that aims to bring attention to the pitfalls of the new mercantilism such as eaton and grossman 1986 dixit and grossman 1986 and horstman and markusen 1986 unlike these studies however the government policies considered here are reactive in the sense that the private sector moves first anticipating the government s response dixit and kyle 1985 carmichael

dumping and dynamic competition abstract when the current output level affects future production costs domestic and foreign profit maximizing firms may set prices below current costs to gain experience antidumping enforcement which poses a barrier to below cost sales by foreign rivals changes the payoff structure of competition and alters the equilibrium decisions of both foreign and domestic firms a comparison of the nash equilibria with and without antidumping rules shows that these rules change market outcomes even when they do not appear to be binding ex post this positive analysis of antidumping enforcement complements previous studies that have considered the motivation for dumping

how pollution taxes may increase pollution and reduce net revenues this paper develops a positive theory of pollution taxation by a federal authority when pollution abatement subsidies are used by local governments environmental and industry lobby groups influence governments with campaign contributions first pollution may increase in the pollution tax because the abatement subsidy increases decreases with the tax and pollution increases decreases in the abatement subsidy this occurs because the lobbying incentives change at a pollution tax reform second pollution taxes may reduce net revenues because subsidy expenditures rise third pollution may increase simultaneously as net revenues fall finally the welfare effect of a pollution tax may be negative

experimental economics hard science or wasteful tinkering i take it that in raising the question what have we learned from experimental economics under the broader umbrella of controversy the point is not to solicit a catalogue of experimental findings but rather to signal the more pointed question are we learning anything at all or at least much that is very useful form experimentation in economics as a practising experimentalist i am convinced that experiments do have the potential to make a significant contribution to knowledge in economics this abstract was borrowed from another version of this item

the hidden costs of renewables promotion the case of crop based biogas abstract this paper finds that specific characteristics of bioenergy investments namely long times to build relatively high variable costs and the managerial ability of corrective actions during the project help bioenergy producers to respond to market uncertainties this effect is shown to compromise the economic effectiveness of bioenergy policies the paper compares the effectiveness of financial and regulatory incentive programs aiming to stimulate production of crop based biogas a stylized stochastic real options based investment model is developed to analyze the investment behavior of biogas producers under alternative policies the model is solved by a numerical approach combining stochastic simulations and the genetic algorithm technique unless bioenergy schemes account for structural characteristics of the bioenergy industry they will tend to encourage investments in unused production capacities this would cause additional welfare costs and benefit mainly crop producers

trade policy to promote entry with scale economies product variety and export potential with scale economies product variety and export potential production of socially desirable varieties of a product may be privately unprofitable if competition from imported varieties of the same general product is in part responsible for this market failure either tariffs or subsidies may be used to promote domestic entry this paper demonstrates that in domestic welfare terms tariffs may be superior to subsidies for this purpose furthermore because domestic firns will export as well as produce for the domestic market tariff protection which induces entry may give rise to intra industry trade that benefits foreigners and domestic residents la politique commerciale pour promouvoir 1 entree de producteurs domestiques dans les cas ou coexistent des e conomies d e chelle une varie te de produits et des possibilites d exporta tion quand coexistent les economies d echelle la variet6 de produits et les possibilit6s d exportation l auteur montre qu il peut etre non profitable au niveau prive de produire une variett de produits socialement d6sirables si c est la concurrence de vari6t6s import6es d un produit gdneral qui est responsable de cette defaillance du march6 on peut utiliser soit les droits de douane soit les subsides pour promouvoir l entr6e de producteurs domestiques ce memoire demontre que l utilisation des droits de douane est une solution pref6rable en termes de bien etre domestique de plus comme les entreprises domestiques vont exporter en plus de produire pour le march6 domestique la protection douaniere qui suscite l entr6e peut aussi donner lieu a du commerce intra industrie qui a des retombees ben6fiques pour les etrangers et pour les residents de l economie domestique

anti dumping and countervailing duties under oligopoly abstract this paper constructs a conjectural variations model of international oligopoly in which the home country s optimal policy responses to the foreign government s subsidies and foreign firms dumping can be calculated some theoretical support is found for tariffs that countervail part of the foreign export subsidy the optimal fraction depends on the size of own and cross effects in demand and on the extent of market competition however no normative case is found for anti dumping duties

sustainability guided promotion of renewable electricity generation in recent years the threat of global climate change high fuel import dependence and rapidly rising electricity demand levels have intensified the quest for more sustainable energy systems this in turn has increased the need for policy makers to promote electricity generation from renewable energy sources guaranteed prices coupled with a buy back obligation for electricity fed into the grid is a popular renewables promotion instrument especially in europe more recently driven mainly by electricity market liberalisation efforts quota targets for the share of renewables in combination with tradable green certificates tgc have received considerable attention tgc offer a greater theoretical potential for economic efficiency gains due to price competition and the greater flexibility assigned to the obliged parties while guaranteed prices and tgc schemes support the operation of renewable energy technology systems bidding schemes for renewable energy generation capacity are used to raise economic efficiency on the plant construction side all of these policy instruments suffer from the shortcoming that they do not explicitly account for the often widely varying environmental social and economic impacts of the technologies concerned in this paper we propose a methodology for the design of renewable energy policy instruments that is based on integrated assessment in particular we argue that using participatory multicriteria evaluation as part of the design of renewable energy promotion policies would make it possible 1 to differentiate the level of promotion in a systematic and transparent manner according to their socio ecological economic impact and 2 to explicitly account for the preferences of stakeholders a further problem of existing tgc and bidding schemes is that diversity of supply could be severely diminished if few low cost technologies were allowed to dominate the renewable energy market to ensure a certain diversity of technologies our scheme suggests the use of different technology bands for technologies that are relatively homogeneous with respect to their maturity

bounded rationality in contingent valuation empirical evidence using cognitive psychology abstract survey based valuation techniques like the contingent valuation method cvm rely particularly on the premise of respondents rationality when answering willingness to pay wtp questions results of cvm surveys have repeatedly put this fundamental assumption into question this study adopts a more realistic view of rationality accounting for respondents limited capacities to process information based on cognitive psychology a technique to detect and analyze the bounds of rationality inherent in wtp statements is developed using an empirical example the influence of bounded rationality on the validity of cvm results is analyzed it is shown that individual differences in information processing play a major role for the validity of cvm responses the results allow new insights into response behavior in dichotomous choice versus payment card elicitation formats from the results of this study recommendations for future survey designs taking into account respondents different information processing modes are developed

regional drivers of on farm energy production in bavaria abstract bavaria s energy policy seeks to increase the share of power supply from renewable sources related to on farm energy production agricultural biogas wind and solar energy from currently 15 to more than 30 in 2021 it is therefore of particular interest for policy makers to identify regional drivers of and barriers to this concept the presented study addresses this issue and applies a spatial regression analysis to bavaria s 71 rural counties the findings indicate significant impacts of technological regional transformation ability agricultural structure degree of professionalization and consolidation of organic farming and neighborhood effects this is in contrast to most geographical factors which seem to be of minor relevance

strategic tariffs and endogenous market structures trade and industrial policies under imperfect competition abstract this paper examines strategic tariff policy tariff induced entry and endogenous market structures in a developing country setting it improves on recent theoretical treatments of optimal trade policy under imperfect competition by allowing for forward looking import substituting investment induced by an anticipated time consistent tariff policy it shows that the optimum tariff is robust across a subset of market structures and cost and demand specifications however it will usually involve insufficient or excessive entry by domestic firms and consequently industrial policy of various kinds is a necessary supplement to strategic tariff policy

decision making under environmental uncertainty abstract the paper s main concern is with different decision making models for environmental issues and with the hypotheses of rationality underlying such models the hypothesis supported here is that most environmental problems are in a context of uncertainty of irreversibility and of complexity we shall explain why stressing the role of these elements implies a reversal of the traditional attitude towards decision making this presupposes a paradigm of economic rationality much broader that that of orthodox economics called procedural rationality our paper is in two parts the first part concerns the limits of the stochastic environmental approaches based on the bayesian decision theory and on a substantive rationality hypothesis the second part concerns the decision making analyses based upon a procedural rationality as well as their ability to take account of the interactions between uncertainty irreversibility and complexity

foreign and domestic multinational presence in the uk the determinants of multinational presence in uk manufacturing industry in 1979 are analysed it is argued that maultinational presence may result from strategic interaction as well as other firm and industry characteristics the determinants of both foreign and uk multinational presence are estimated using a dataset that enables both types of multinational to be indentified results show an important effect of both scale and concentration on multinational presence

agent based spatial models applied to agriculture a simulation tool for technology diffusion resource use changes and policy analysis abstract this paper presents a spatial multi agent programming model which has been developed for assessing policy options in the diffusion of innovations and resource use changes unlike conventional simulation tools used in agricultural economics the model class described here applies a multi agent cellular automata ca approach by using heterogeneous farm household models and capturing their social and spatial interactions explicitly the individual choice of the farm household among available production consumption investment and marketing alternatives is represented in recursive linear programming models adoption constraints are introduced in form of network threshold values that reflect the cumulative effects of experience and observation of peers experiences the model s economic and hydrologic components are tightly connected into a spatial framework the integration of economic and hydrologic processes facilitates the consideration of feedback effects in the use of water for irrigation the simulation runs of the model are carried out with an empirical data set which has been derived from various data sources on an agricultural region in chile simulation results show that agent based spatial modelling constitutes a powerful approach to better understanding processes of innovation and resource use change

reconciling theory and practice an alternative conceptual framework for understanding payments for environmental services article i nfo this article provides an alternative and novel theoretical approach to the conceptualization and analysis of payments for environmental services pes we devote special emphasis to institutional and political economy issues which have been somewhat neglected in the literature on pes we argue that the coasean and pure market approach dominating the conceptualization of pes in the literature cannot be easily generalized and implemented in practice by contrast taking into account complexities related to uncertainty distributional issues social embeddedness and power relations permits acknowledging the variety of contexts and institutional settings in which pes operate the alternative approach presented in this introductory article to the special section may be more appealing to pes practitioners since while avoiding restrictive and prescriptive standpoints it allows some key sources of complexities they usually deal with on the ground to be more easily understood

bank size and household financial sentiment surprising evidence from university of michigan surveys of consumers we analyze comparative advantages disadvantages of small and large banks in improving household sentiment regarding financial conditions we match sentiment data from the university of michigan surveys of consumers with local banking market data from 2000 to 2014 surprisingly the evidence suggests that large rather than small banks have significant comparative advantages in boosting household sentiment findings are robust to instrumental variables and other econometric methods additional analyses are consistent with both scale economies and the superior safety of large banks as channels behind the main findings these channels appear to more than offset stronger relationships with and greater trust in small banks
