Considerable efforts have been made in recent years to produce detailed topologies of the Internet, but so far these data have been overlooked by economists. In this paper, we suggest that such information could be used to characterize both the size of the digital economy and outsourcing at country level. We analyse the topological structure of the network of trade in digital services (trade in bits) and compare it with the more traditional flow of manufactured goods across countries. To perform meaningful comparisons across networks with different characteristics, we define a stochastic benchmark for the number of connections among each country-pair, based on hypergeometric distribution. Original data are filtered so that we only focus on the strongest, i.e. statistically significant, links. We find that trade in bits displays a sparser and less hierarchical network structure, which is more similar to trade in high-skill manufactured goods than total trade. Moreover, distance plays a more prominent role in shaping the network of international trade in physical goods than trade in digital services.  相似文献

The board of directors plays an important role in corporate governance. It is an internal mechanism that controls and monitors the actions of managers and aligns the utility functions between corporate owners and managers. The board of directors performs multiple functions that concern, for example, the replacement of the managers, financial policy, the preparation of strategic plans and other actions that affect the performance of the company. The board plays an important role since on the one hand it controls the actions of management and on the other it advises the management regarding the strategies to be adopted. In this study, 100 announcements regarding the appointment of the board of directors of 100 Italian listed companies during the period 2012–2014 are investigated. The results show a positive reaction within 20 days around the announcement date. In four of the six time windows, cumulative abnormal returns (CARs) are positive and statistically significant. The positive reaction of the market would appear, however, to be linked more to the composition of the board of directors than to the size of the board of directors.  相似文献

Building on a biopolitical understanding of the economic crisis, this essay contends that the occurrence of the crisis warns that life is not a real commodity but — to put it in Karl Polanyi's terms — a ‘fictitious commodity’. This means that life cannot be integrally subsumed within the economy, and therefore the crisis is to be seen as a pathological way in which societies react to the pervasiveness of capitalist relations, showing the illusory character of self‐regulating markets and ownership ideologies. Two mutually contradictory biopolitical responses to the neoliberal crisis, led by the state and grassroots movements respectively, are discussed in the concluding section of the essay.  相似文献

We formulate a two‐sector New Keynesian economy featuring sectoral heterogeneity along three dimensions: price stickiness, consumption goods durability, and the usage of input materials in production. These factors affect both inter‐sectoral and intra‐sectoral stabilization. We examine the welfare properties of simple rules that react to alternative measures of final goods price inflation. Due to factor demand linkages, the cost of production in one sector is influenced by price‐setting in the other sector. Therefore, measures of aggregate inflation weighting sectoral prices based on their relative stickiness do not allow one to keep track of the effective speeds of sectoral price adjustment.  相似文献

The aim of this paper is to explore the role played by cost accounting in Italy's Industrial Mobilization system and in the largest firm manufacturing weaponry, Ansaldo of Genoa, during WWI. While in other countries such as the UK and the USA, efficiency in buying and managing war material was an important part of military strategy, in Italy, various factors impeded it. This paper focuses on contracting procedures adopted by the Ministry of War and Ministry of Munitions and looks at the cost accounting practices in Ansaldo to see how costs were determined and how prices were set. We found a paradox. On the one hand, despite knowledge of costing, the government did not impose cost controls on the producers of war material, nor on their profit rates. On the other hand, examining Ansaldo's cost sheets we discover they underestimated their production costs leading the firm to losses despite its favorable political position. This paper contributes to the theoretical debate about the relationships between accounting and war in the Italian context where lobbying, collusion, bribery and private interests dominated the administrative behavior of public and private actors instead of efficiency, accountability and honesty.  相似文献

The no‐arbitrage relation between futures and spot prices implies an analogous relation between futures and spot daily ranges. The long‐memory features of the range‐based volatility estimators are analyzed, and fractional cointegration is tested in a semi‐parametric framework. In particular, the no‐arbitrage condition is used to derive a long‐run relationship between volatility measures and to justify the use of a fractional vector error correction model (FVECM) to study their dynamic relationship. The out‐of‐sample forecasting superiority of FVECM, with respect to alternative models, is documented. The results highlight the importance of incorporating the long‐run equilibrium in volatilities to obtain better forecasts, given the information content in the volatility of futures prices. © 2011 Wiley Periodicals, Inc.

This article examines a sample of German pharmaceutical firms to highlight the strategic reasons why firms participate in various intellectual property (IP) marketplaces, both proprietary (patents and copyrights) and non-proprietary (open source and non-patented technology). The obstacles that prevent these marketplaces from functioning efficiently are also investigated. The analysis suggests that IP policy must embrace all IP forms and must recognise that IP marketplaces do not work “automatically” but suffer many institutional failures.  相似文献

This paper compares the characteristics of derivatives users and non-users, using data from U.S. savings associations during 1993–1994. Unlike prior studies, the data used in this analysis are market values of assets and liabilities. Market values were obtained from the base case (no interest rate change) in the Office of Thrift Supervision's (OTS) Net Portfolio Value Model. This model calculates the value of all of a thrift's positions to calculate the value at risk. We determine the consistency of theories of derivatives use with the characteristics of derivatives users.  相似文献

We present a theory of entry through spinoffs where workers generate ideas and possess private information concerning their quality. Because quality is privately observed, adverse selection implies that the market can only offer a price that reflects the average quality of ideas sold. Only workers with good ideas decide to spin off, whereas workers with mediocre ideas sell them. Existing firms pay a price for ideas sold in the market that implies zero expected profits. Hence, firms’ project selection is independent of firm size, which can lead to scale‐independent growth. This mechanism results in invariant firm‐size distributions that resemble the data.  相似文献
