Growth Rate and Level Effects,the Stability of the Adjustment of Capacity to Demand and the Sraffian Supermultiplier

Abstract

The paper presents a simple but complete formal version of the Sraffian supermultiplier model in which (i) growth is led by the autonomous components of demand that do not create capacity; (ii) private productive investment is an induced expenditure; and (iii) income distribution is exogenous. We show that the main results of the long-period and fully adjusted versions of the model in terms of growth rate and level effects are quite similar and therefore that such results in no way require the full adjustment of capacity to demand. We then analyze a simple set of sufficient dynamic local stability conditions that allow the long-period positions to gravitate towards the fully adjusted position in which capacity is adjusted to demand and that also provide the upper limit to demand-led growth paths. Finally, we show how some critics of the model have misinterpreted it as being supply-led and how this has led to a further confusion between the analysis of the tendency towards a constant value of the capacity-saving-determined warranted rate of growth and the proper stability analysis of the opposite process of adjusting capacity to demand (which tends to adjust the warranted rate endogenously to the growth rate of autonomous demand).     

Who Owns Guaraná? Legal Strategies,Development Policies and Agricultural Practices in Brazilian Amazonia

This paper offers a historical perspective on the interactions between legal standards and agricultural practices relating to guaraná, an energy‐inducing Amazonian plant that is in increasing demand. Guaraná is managed in a number of socio‐technical contexts, ranging from the fizzy drink industry to alternative agro‐ecological farming systems, and is subject to a great many legal rules that determine the conditions for its use and appropriation. The paper shows how, in guaraná's native region of Maués, Brazilian Amazonia, various stakeholders including the indigenous population, associations of smallholdings and multinationals use legal standards in order to gain prerogatives over the plant and/or win a share of a growing market. In spite of the fact that the plant has been domesticated by the Sateré‐Mawé and that traditional knowledge has been recognized in Brazil, to a certain extent history has dispossessed them of their rights to guaraná. New political and economic circumstances have favoured those actors committed to strategies of agricultural modernization and industrial processing. On the other hand, the ecologization of agriculture and the increasing numbers of instruments for differentiating production (such as fair trade, organic farming and geographical indications) seem to be favouring diversification in the methods of managing guaraná, as well as a certain re‐appropriation of the plant by local communities.     

Selling two environmental services: In-kind payments for bird habitat and watershed protection in Los Negros, Bolivia

Marketing several environmental services from a single area can help access diverse sources of funding and make conservation a more competitive land use. In Bolivia's Los Negros valley (Department of Santa Cruz), bordering the Amboró National Park, 46 farmers are currently paid to protect 2774 ha of a watershed containing the threatened cloud-forest habitat of 11 species of migratory birds. In this payment for environmental services (PES) scheme, annual contracts prohibit tree cutting, hunting and forest clearing on enrolled lands. Farmer-landowners as service providers submit to independent yearly monitoring, and are sanctioned for non-compliance. Facilitated by a local NGO, Fundación Natura Bolivia, one service buyer is an international conservation donor (the US Fish and Wildlife Service) interested in biodiversity conservation. The second service users are downstream irrigators who likely benefit from stabilized dry-season water flows if upstream cloud forests are successfully protected. Individual irrigators have been reluctant to pay, but the Los Negros municipal government has on their behalf contributed ~ US$4500 to the scheme. The negotiated payment mode is annual quid pro quo in-kind compensations in return for forest protection. Predominantly, payments are made as “contingent project implementation”, transferring beehives supplemented by apicultural training. With regard to service provision, environment committees and education programs have increased awareness in downstream communities of the probable water-supply reduction effect of continued upstream deforestation. External donors have funded subsequent studies providing basic economic, hydrological and biodiversity data, and covered PES start-up (~ US$40,000) and running transaction costs (~ US$3000 per year over the last three years). The greatest challenges in the development of the PES mechanism have been the slow process of building trust between service buyers and providers, and in achieving clear service-provision additionality.     

Economic Value of the Carbon Sink Services of Tropical Secondary Forests and Its Management Implications

This paper explores the economic feasibility of secondary forest regeneration and conservation as an alternative in the campaign addressing the problem of global warming. Detailed measurements of tropical secondary forests over time, in different ecological zones of Costa Rica, are used to evaluate carbon storage models. The paper addresses key issues in the international discussion about cross- and within-country compensation for carbon storage services and illustrates a method to compute/predict their economic value over time under a variety of scenarios. The procedure is applicable to other developing countries where secondary forest growth is increasingly important.     

The legacy of European Capitals of Culture to the “smartness” of cities: The case of Guimarães 2012

The objective of the paper is to examine the extent to which the legacy of European Capitals of Culture (ECOC) increases the “smartness” of cities. A qualitative approach based on semi-structured interviews and desk research was used to assess the impact on the smart city's dimensions hypothesized by Giffinger et al. (2007 Giffinger, R., Fertner, C., Kramar, H., Kalasek, R., Pichler-Milanovic, N., &; Meijers, E. (2007). Smart cities—Ranking of European medium-sized cities (Report). Vienna University of Technology Retrieved November 25, 2015, from http://www.smart-cities.eu/download/smart_cities_final_report.pdf [Google Scholar]). The research revealed that this kind of mega-event reinforces the smartness of the city in which it is hosted in terms of attributes such as living, economy, people and environment. No significant legacy is observed with respect to the mobility dimension.     

Combatant recruitment and the outcome of war

What determines who wins a civil war? We propose a simple model in which the power of each armed group depends on the number of combatants it is able to recruit. This is in turn a function of the relative ‘distance’ between the group leadership and potential recruits. We emphasize the moral hazard problem of recruitment: fighting is costly and risky so combatants have the incentive to defect from their task. They can also desert altogether and join the enemy. This incentive is stronger the farther away the fighter is from the principal, since monitoring becomes increasingly costly. Bigger armies have more power but less monitoring capacity to prevent defection and desertion. This general framework allows a variety of interpretations of what type of proximity matters for building strong cohesive armies ranging from ethnic distance to geographic dispersion. Different assumptions about the distribution of potential fighters along the relevant dimension of conflict lead to different equilibria. We characterize these, discuss the implied outcome in terms of who wins the war, and illustrate with historical and contemporaneous case studies.     

Entry‐Timing Advantages in Renewable Natural Resources Industries

In this paper, we explore the conditions of entry‐timing advantages in renewable natural resource industries. Drawing from behavioural theory of the firm, we classify firms in two groups depending on the different heuristics used to make entry decisions when facing the cyclical endogenous nature of these industries: crowd firms are procyclical, making decisions based on the current phase of the industry cycle, whereas anti‐crowd firms follow a countercyclical strategy, making uncertain, and risky decisions by estimation of the next phase of the cycle. Therefore, anti‐crowd firms anticipate the deployment of resources each cycle, potentially gaining entry‐timing advantages beyond those provided by traditional competitive isolating mechanisms. Through a mathematical simulation of a performance feedback model, we reveal that the entry‐timing advantage of the anti‐crowd group becomes possible when the rivalry in the industry and the price sensitivity of competitors are high, and when the time required to deploy the resources is short.     

Ownership Structure, Technological Endowment and Competitive Advantage: Do Democracy and Business Fit?

The current study provides a model that aims to explain the origin of the competitive advantage of organizations in terms of the ownership structure. We have also studied the interactions between IT use and ownership structure. To reach these objectives, we have classified the organizations in two groups using the cooperative character criterion. The results show that cooperative firms achieve a superior competitive advantage regardless of the amount of IT that the firms use. The study is focused on the Spanish Pharmaceutical Distribution Industry.     

Exploring the role of memory for self‐selected ad experiences: Are some advertising media better liked than others?

Advertising media are associated with different degrees of self‐selected versus intrusive ad experiences. The role of such media differences in attitudes toward advertising was explored in a nationwide survey. The survey provides a national picture of attitudes toward specific ad media ranging from advertising media that deliver highly self‐selected ad experiences (catalogs and business classifieds) to highly intrusive ones (TV). A total of 2,514 adults were surveyed regarding their opinions about ads in (1) TV, (2) radio, (3) catalogs, (4) business classifieds, (5) out‐of‐home, or (6) advertising in general. Media that allow for self‐selected experiences, where perceived interest in an ad is the basis for attention to it, were evaluated much more favorably than more intrusive advertising media. Catalogs and business classifieds elicited the most favorable opinions; TV advertising elicited the least, and these media differences generally cut across demographic lines. Also, although more educated and affluent consumers generally held less favorable views of advertising, preliminary results suggested that this did not hold true for media that allow for self‐selected processing. An additional study suggested that memory for advertisements plays a significant role in the evaluation of a self‐selected ad medium (catalogs). That is, consumers' strongest memories are for those ads to which they paid the most attention, and consequently these engaging ads have a disproportionate influence on opinions toward the ad medium. © 2004 Wiley Periodicals, Inc.
