Among the many insightful contributions of Thorstein Veblen and John R. Commons is that habits of thought matter. Habits of thought condition policy and place limits on what is possible. This article tackles five habits of thought that inhibit the process of economic development. These include: (i) the confusion of economic development with economic growth; (ii) the crowding-out hypothesis; (iii) the concept of the steady state economy; (iv) the peak oil hypothesis; and (v) the inevitability of economic progress. None of the discussions in this article are intended to minimize the importance of other very real constraints to the development process. A few of these other constraints are war, racism, sexism, political instability, corruption, and climate change.  相似文献

This paper estimates the revenue potential of a financial transaction tax (FTT) for US financial markets. We focus on analyzing the revenue potential of the Inclusive Prosperity Act that was introduced in the US House of Representatives in 2012 and the US Senate in 2015. The tax rates stipulated in this Act include 0.5% (50 basis points (bps)) for all stock transactions, 0.1% (10 bps) for all bond transactions and 0.005% (0.5 bps) on the notional value of all derivative trades. We examine three sets of evidence to generate potential revenue estimates: 1) the levels of transaction costs in US financial markets over time and within the range of financial market segments; 2) the extent of trading elasticities under various trading conditions; and 3) the current level of trading activity in US financial markets. Based on this evidence, we conclude that a US FTT operating at the tax rates stated above would generate about $220 billion per year, equal to about 1.2% of the current US GDP.  相似文献

Plural forms exist when managers use two owners to perform one activity. Franchising is a plural form explained by agency theory, however, the theory is unable to explain two franchisor actions: 1) allowing franchisees to own multiple outlets and 2) co‐locating company‐owned and franchised outlets. We use research that describes a symbiosis between company‐owned and franchised outlets to extend agency theory and explain these actions. Our investigation of ownership patterns among 4,339 outlets of 16 plural form franchisors is consistent with our theory that multi‐outlet franchising is cost efficient and that co‐location occurs when franchisors fill market gaps left by franchisees.

Innovation is central to the survival and growth of firms, and ultimately to the health of the economies of which they are part. A clear understanding both of the processes by which firms perform innovation and the benefits which flow from innovation in terms of productivity and growth is therefore essential. This paper demonstrates the use of a conceptual framework and modeling tool, the innovation value chain (IVC), and shows how the IVC approach helps to highlight strengths and weaknesses in the innovation performance of a key group of firms—new technology‐based firms. The value of the IVC is demonstrated in showing the key interrelationships in the whole process of innovation from sourcing knowledge through product and process innovation to performance in terms of the growth and productivity outcomes of different types of innovation. The use of the IVC highlights key complementarities, such as that between internal R&D, external R&D, and other external sources of knowledge. Other important relationships are also highlighted. Skill resources matter throughout the IVC, being positively associated with external knowledge linkages and innovation success, and also having a direct influence on growth independent of the effect on innovation. A key benefit of the IVC approach is therefore its ability to highlight the roles of different factors at various stages of the knowledge–innovation–performance nexus, and to show their indirect as well as direct impact. This in turn permits both managerial and policy implications to be drawn.  相似文献

Firms increasingly rely on suppliers to perform tasks in new product development (NPD). Research has only recently begun to focus on the processes to manage this supplier development responsibility, and has hardly investigated how firms collect and analyze information regarding the cost and performance of alternative supplier offerings. Our study addresses this gap, through a field survey among 144 paired samples of project leaders and cost analysts involved in the same NPD projects. On the basis of literature and qualitative research, we conceptualize a substantive model. We first use a substantive validity assessment to vet the measures for the proposed constructs. We then test the substantive model with structural equation modeling using a multiple‐sample analysis. The results strongly show that monetary quantification of differences and detail gathering play significant roles in successfully leveraging supplier development responsibility. The findings support the hypothesis that the extent of development responsibility that suppliers have leads the development team to a more focused monetary quantification of the differences in alternative supplier offerings. Monetary quantification of differences has a significant, positive effect on the extent of supporting‐detail gathering and on the development speed of the project, whereas supporting‐detail gathering has a significant, positive effect on the product advantage of the new product as well as development speed. These findings are robust across the two functional perspectives. Our study complements the literature on interfirm control and monitoring by demonstrating the effects of selective and focused output controls.  相似文献

For many less developed countries production of high quality output is a precondition for firms to become exporters. Institutional deficiencies that raise costs of high quality production therefore limit the positive impact that trade facilitation can have on income. Consequently, institutional reforms that reduce costs of high quality production and trade reform have synergistic effects. In contrast, institutional reforms that reduce costs of low quality production (e.g., reforms that disproportionately benefit small businesses) interfere with the impact of trade reform. We obtain these results in a heterogeneous firm model that displays standard “industry rationalization” responses to reduced trade costs.  相似文献

The presence of conflicting cues about what is legitimate provided by various stakeholders, begs the question of how the legitimacy of contested institutionalized practices is justified. Recent critique of tax minimization strategies exemplifies this difficulty: on one hand, practitioners need to increase shareholders' profits; on the other, a growing number of stakeholders push for ‘fairer’ corporate tax payments. Conducted during a time of public criticism of Australian corporate tax strategies, our study draws on justifications of corporate tax minimization strategies by senior tax practitioners and corporate submissions to a Senate Inquiry on corporate tax avoidance. The study explores how legitimacy judgements come under pressure by conflicting cues. Through the application of Boltanski and Thévenot's (2006) Economies of Worth (EW) framework, we advance legitimacy scholarship by clarifying what constitutes situated judgements in times of instability. Our work puts forward the concept of perceived forecasted consensus as a guide for individuals in making situated legitimacy judgements in times of instability.  相似文献

The zero bound on interest rates introduces a new dimension to the trilemma in international policy. The openness of the international financial market might render monetary policy ineffective, even within a system of fully flexible exchange rates, because shocks that lead to a liquidity trap in one country are propagated through financial markets to other countries. However, the effectiveness of monetary policy can be restored by the imposition of capital controls. We derive the optimal response of monetary policy to a global liquidity trap in the presence of capital controls. We show that, even though capital controls might facilitate effective monetary policy, capital controls are not generally desirable in terms of welfare.  相似文献

目的:血液透析相关的血流感染是一个严重的公共健康问题,因为加拿大的血液透析病人从1996年到2005翻了一番。本研究目的在于确定加拿大医院血流感染的成本,估算在综合性医院中建立感染控制项目的成本,并进行成本-效益分析。材料与方法:用加拿大医院感染监测项目的数据来估算医院血流感染的发生率。用加拿大健康信息所数据来估算2004年加拿大平均一次血流感染住院的额外成本。建立和维护一个感染控制项目的成本用美国疾病预防与控制中心1985年的成本换算为2004年的加拿大成本来估算。假设感染控制项目能降低医院血流感染病例的20%~30%。结果:2004年的加拿大15278名血液透析病人中估计共有2524人发生血流感染。全年用于治疗血流感染的成本估计为4901万加元。医院血流感染预防和人力资源的总投资成本为815万加元。建立医院感染控制项目后能带来1452万加元的医疗成本节约。效益成本比在1.0:1到1.8:1之间。结论:本研究提供的证据表明,如果医院感染控制项目能降低20%~30%的感染,该项目的经济效益将远超过增加的成本。医院感染控制项目将带来双重效益:节约货币成本的同时改善医疗质量。  相似文献
