Blogs provide a dynamic interactive medium for online discussion, consistent with communal constructivist pedagogy. The author of this article describes and evaluates a blog assignment used in the teaching and assessment of a small (40–60 students) introductory economics course. Using qualitative and quantitative data collected across four semesters, students’ participation in the blog assignment is found to be associated with student ability, gender, and student perceptions of the blog. Importantly, students with past economics experience do not appear to crowd out novice economics students. Student performance is positively associated with the quality of their blog participation after controlling for student ability, suggesting that a focus on quality of student engagement could further improve learning outcomes. Students generally report overall positive experiences with the blog assignment.  相似文献

Maintenance consumption is an expense recovered in product prices, yet also a source of taste satisfaction which must be exhausted, rather than reinvested, from the capital affording it. This riddle is solved in the duplication rules: the cost of maintenance consumption is recovered in pay and prices, but an equal flow is exhausted from the human capital of the worker earning the pay. The rules impact tradition in several ways. If output is defined in principle as value added, then it cannot also be described as consumption plus net investment without double-counting the maintenance consumption recovered in prices. Also rate of return in the stationary state is not zero, but is the rate sufficient to offset the exhaustion of individual human capital. The rules lead to new insights into economic return, and support an argument that all growth at the scale of closure is due to productivity gain rather than to thrift.  相似文献

Abstract

In 1930, Richard Kahn became a fellow of King's College, Cambridge, on the basis of his book-length dissertation ‘The Economics of the Short Period.’ It was finally published in the 1980s. Why did he not publish his thesis in the 1930s, when it would have made a substantial impact? We present two arguments. In 1932/33, Joan Robinson published many of Kahn's main ideas, rendering subsequent publication by him derivative. And by the mid-1930s, Kahn discovered that parts of his dissertation left untouched by Robinson were no longer new or distinctive because of rapid progress in research on imperfect and monopolistic competition.  相似文献

Summary. We ask whether communication can directly substitute for memory in dynastic repeated games in which short lived individuals care about the utility of their offspring who replace them in an infinitely repeated game. Each individual is unable to observe what happens before his entry in the game. Past information is therefore conveyed from one cohort to the next by means of communication.When communication is costless and messages are sent simultaneously, communication mechanisms or protocols exist that sustain the same set of equilibrium payoffs as in the standard repeated game. When communication is costless but sequential, the incentives to whitewash the unobservable past history of play become pervasive. These incentives to whitewash can only be countered if some player serves as a neutral historian who verifies the truthfulness of others reports while remaining indifferent in the process. By contrast, when communication is sequential and (lexicographically) costly, all protocols admit only equilibria that sustain stage Nash equilibrium payoffs.We also analyze a centralized communication protocol in which history leaves a footprint that can only hidden by the current cohort by a unanimous coverup. We show that in this case the set of payoffs that are sustainable in equilibrium coincides with the weakly renegotiation proof payoffs of the standard repeated game.Received: 30 September 2002, Revised: 5 August 2003, JEL Classification Numbers: C72, C73, D82.We wish to thank an Associate Editor and Dino Gerardi as well as seminar participants at Arizona State, Columbia, Duke, Georgetown, Indiana, Montreal, Princeton, Rochester, Vanderbilt, VPI, the 2001 NSF/NBER Decentralization Conference, the Summer 2001 North American Econometric Society Meetings, and the Midwest Theory Conference, 2000, for useful comments and suggestions.

Most mainstream economists regard the principles of ‘rational choice’ theory as the only foundation of economics and insist that macroeconomics be based on those principles. These include certainty or certainty-equivalence, which followers of Keynes reject. Macrofoundations of microeconomics are often proposed instead. We argue that the issue is more complex and explain why it is unlikely that a logically watertight fit between the two levels of analysis will ever be achieved. The complex interactions within and between the two levels suggest that it is unhelpful to assign foundational status to either level. We examine Keynes’ General Theory is examined as an example and compromises are found to fit the two together. It is argued that compromise is inevitable and that good theorising entails defending the compromises made.  相似文献

The institutional environment of science differs across countries. Its particularities have an impact on productivity of scientific enterprise in terms of both research and teaching. Reform of the system of higher education occupies an important place in programs of catch-up modernization. Attempts to replicate Western institutional arrangements and organizational designs in this area have been undertaken in Russia since the very beginning of economic and political reforms of the 1990s. This paper considers a particular transplant, the Higher School of Economics (HSE) established in 1992, and its subsequent evolution. A structural analysis shows its divergence from the organizational patterns that served as a model. The HSE case is compared with several "representative" Western universities as well as other Russian universities. When explaining divergent patterns between the HSE and the Western counterparts, special attention is paid to the issue of power relationships and their role in the functioning of the scientific organization. The paper aims to contribute to the discussion of "cultural entrepreneurs" and their motivation.  相似文献

Abstract

The developments of political economy in France between 1750 and 1776 did not allocate a central place to the discussion of the nature and functions of money. The object of this paper is to account for this fact and what it denotes: the disappearance of money as a central object in the discourse on economy and society. We outline the context of this mutation in relation to the ideas of Montesquieu, Gournay and Forbonnais. The actors of this change will then be considered: the promoters throughout these years of ‘philosophie économique’ i.e. Quesnay, the Physiocrats and Turgot. An analysis of these authors, together with a founder of this perspective, Boisguilbert, will show how the status and role of money was modified and illuminate the issues involved. This transformation can be related to the affirmation of a new political discourse whose foundations are rooted in economic interest.  相似文献

Why has the military dimension of the US-Japan relationship remained the central point of reference for Japanese foreign relations, despite the demise of the Soviet Union? Why has Japan, deepening economic interdependence notwithstanding, remained politically distant from East Asia? Based on analysis of statements by Japanese and US political elites and academics regarding the US-Japan alliance, this article argues that the rise of China, coterminous with the rise of ‘Asia’, challenges the notion of the ‘West’ as, according to standards of industrial modernity, a superior social and political order. These moving ideational boundaries question Japan’s position as the most advanced Asian nation and member of the (Western) international society of states. Therefore, the US-Japan alliance has since the mid-1990s become increasingly important for securing Japan in the ‘West’ and the ‘West’s boundaries in East Asia.  相似文献

Very few contributions have been published in English on the Italian geopolitical tradition of the interwar years. This is rather surprising, given the fact that, after Geopolitik, Italian geopolitics was one of the largest and most significant in Europe. This article aims to fill this void, by offering a detailed and critical investigation into this intellectual production. Although the article traces the origins of Italian geopolitics back to the 1920s, its main focus is on Geopolitica (1939–1942), the journal which, more than any others, embodied the attempts to give Italy its own geopolitics. Despite its ambitious proposal to become the ‘imperial-geographical consciousness’ of the Fascist regime, Geopolitica remained largely confined within the circle of academic geography and ultimately also failed to influence the development of Italian geographical tradition.  相似文献

Inventors and organizational assets are inputs of inventive activities which are often provided at a global scale, where countries might specialize in the provision of one or the other type of inputs. We introduce a new patent-based metric, the ‘inventor balance’, to quantify this type of functional specialization, which we discover to be considerable, and we propose a conceptual framework to explain it. We observe a progressive ‘decoupling’ of national sub-systems providing respectively inventors and organizational assets. Moreover, we find that countries with a high level of innovativeness relative to their economic development, high technological specialization, and strong individualistic cultural traits, contribute relatively more inventors than organizations to the global production of inventions.  相似文献

We evaluate the sensitivity of distance decay in individuals’ stated willingness to pay (WTP) for water quality improvements in eutrophied lakes. We extend the standard model of contingent valuation (CV) by allowing individuals to adopt a sequential evaluation process consisting of two decision stages. In the first stage respondents decide whether they are ‘protesters’, have a WTP   \(=\)   ‘true zero’ or a \(\hbox {WTP}>0\) . Conditioned on a strictly positive WTP, we use Lee’s selectivity-corrected model to determine the magnitude of their WTP in the second stage. Using CV survey data from Norway we find significant distance decay in the first stage classification of respondents as ‘protesters’, ‘true zero’ WTP, or positive WTP. In the second stage model for positive WTP responses, we find little or no significant relationships when correcting for selection. Results suggest that previous findings of significant distance decay in contingent valuation of lake and river water in Europe may be driven by the definition of ‘protest’ and ‘true zero’ respondents. We find that WTP for water quality may be more useful as a qualitative indicator of political support for user financed water quality measures, than as a cardinal measure of marginal utility of water quality improvements.  相似文献

The relationship between job satisfaction levels and the remuneration of non-owner managers employed by a sample of 97 UK small and medium sized enterprises (SMEs) is investigated. The main empirical findings are that relative remuneration levels appear to be largely explained by differences in human capital and job/firm characteristics and that job satisfaction is positively related to deviations from these estimated comparison-income levels. Moreover, the equity theory expectation that individuals with the least prospect of redressing payment inequities will have the greatest incentives to respond to payment inequities by congitive adjustment is also supported. The results indicate that job satisfaction levels for individuals expecting to remain in their current post are not significantly affected by current payment inequities. For those managers who expect to move firms, the amount of payment inequity has a significantly positive effect upon their job satisfaction.  相似文献

In this article, I first expound John Kenneth Galbraith’s general theory of power. Galbraith always took into account phenomena of power in economics, and shed light on the power of economists in particular. I then show how the reaction of conservatives to the broadcasting of the Age of Uncertainty highlights the relevance of Galbraith’s theory. Letters exchanged by conservative Lords in an effort to fight against Galbraith’s ideas paradoxically illustrate his theory. This leads to questions about the status of economists, popularizers, and experts. Finally, I argue that convictions have a crucial role in scientific production, and that Robert Solow’s distinction between the “serious scholars” and the proselyte economist is irrelevant because of its incapacity to understand how economists produce knowledge.  相似文献

Solving large scale optimisation problems over space and time quickly generates a computational impasse, termed the ‘curse of dimensionality’. This severely limits the practical use of economic models, especially for determining the effects of climate change and protectionist trade policies. In this paper, we employ an innovative approach to solving (otherwise unsolvable) large scale systems through the use of parallel processing methods and a proper ordering of variables and equations in a ‘Nested Doubly Bordered Block Diagonal’ form. We illustrate how the approach can be used to solve an intertemporal CGE model with more than 500 million equations. Using existing damage functions, the framework allows us to determine the impact of climate change on long-run economic growth for 112 countries as a result of the effect of sea-level rise on land endowments, variation in crop yields and productivity and shifts in the demand for energy and transportation. We also compare our solution to more common (and smaller dimensional) recursive methods, in terms of both the economic effects of climate change and potential increases in trade barriers, showing the power and efficiency of our computational approach and parallel processing routine.  相似文献
