This paper uses Census microdata to examine how starting a business as a franchise rather than an independent business affects its survival and growth prospects. We assess factors that influence the decision to become a franchisee and use various empirical approaches to correct for selection bias in our performance analyses. We find that franchised businesses on average exhibit higher survival rates than independent businesses; but importantly, the difference is small compared with claims in the trade press. The effect is also short lived: conditional on surviving a year or two, we no longer find survival (or growth) differences. We then explore two potential sources for this small survival advantage, namely franchisors’ screening process and the benefits arising from the brand and business know‐how provided by franchisors. We find evidence that both of the sources contribute to the franchising advantage. 相似文献

The study examines the information content of press announcements of S&P 400 additions between 2002 and 2007. Prior research into stock index additions has explained the positive valuation effects of additions to S&P indices mostly in terms of the price pressure hypothesis and downward sloping curve hypothesis. The two hypotheses attribute the positive market reaction purely to index-fund buying rather than information effects of announcements. My empirical investigation further reinforces the credibility of the information hypothesis by showing that the market varies its response to added firms depending on the information released about them at the announcement. The analysis demonstrates that the mode of addition, exchange listing, reason for index change, and firm size can modulate valuation effects of stock index additions. The paper also strengthens the argument that announcements of additions to an S&P index contain new signals about the industries represented by the added firms. Positive and significant wealth effects are exclusively attributable to ??non-member?? rival firms. Overall, the results imply that the market discerns and rewards firms that come from outside the S&P universe (pure additions) and rival firms that are not part of a target index. 相似文献

This paper describes the role of R&D and analyse its impact on productivity in the Czech economy in a CDM model. Four CIS waves (2001, 2003, 2006, and 2008) were used in the CDM model. The estimated low innovation input elasticity around 9 % describes the Czechs as poor innovators in the EU. This economy was a developing country until 2006 and we have observed a substantive FDI inflow since 1998. Multinationals have a higher sales share now and are an essential part of the economy. Multinationals engage less in innovation, but innovating MNEs spend more on R&D per employee and appropriate more from their innovated goods. The FDI inflow was a form of innovation wave. Innovation output is an important determinant for boosting productivity among SME’s. Public support had positive effect on innovation intensity; however, no additional effect on innovation output. 相似文献

This paper presents a PDE approach in a Markovian setting to hedge defaultable derivatives. The arbitrage price and the hedging strategy for an attainable contingent claim are described in terms of solutions of a pair of coupled PDEs. For some standard examples of defaultable claims, we provide explicit formulae for prices and hedging strategies. 相似文献

Since 1990 the telecommunication sector in Poland has been undergoing rapid development and modernization. It is heavily dominated by Telekommunikacja Polska SA (TP SA), a state-owned company which is split into 10 regional directorates. Although TP SA enjoys a legal monopoly only over international traffic, it is a de facto monopolist in the Polish market too. Apart from difficulties in funding local telephone operations, many of the difficulties facing private competitors to TP SA focus on interconnection and pricing issues. The Anti-monopoly Office, which seeks to restrict unfair competition and restrictive business practices, has been monitoring the compliance of TP SA with the statutory standards. In its business practices TP SA has been reluctant to meet the required standards, particularly these relating to the setting of tariffs. This has been found to have a restrictive effect on the emergence of competition in the form of local operators. 相似文献

We present work concerning the formal specification of business processes. It is of substantial benefit to be able to pin down the meaning of business processes precisely. This is an end in itself,
but we are also concerned to do so in order that we might prove properties about the business processes that are being specified.
It is a notable characteristic of most languages for representing business processes that they lack a robust semantics, and
a notable characteristic of most commercial Business Process Management products that they have no support for verification
of business process models. We define a high-level meta-model, called
Liesbet
, for representing business processes. The ontological commitments for
Liesbet
are sourced from the YAWL workflow patterns, which have been defined from studies into the behavioural nature of business
processes. A formal characterisation of
Liesbet
is provided using Milner’s Calculus of Communicating Systems (CCS). In this article, we omit some of the technical details
of this characterisation and instead present the essential features by means of an abstract machine language, called LCCS.
We also explain how we have facilitated the verification of certain properties of business processes specified in
Liesbet
, and discuss how
Liesbet
supports the YAWL workflow patterns. We include a simple three-part example of using
Liesbet
. 相似文献

We explore the country-specific institutional characteristics likely to influence an individual’s decision to become an entrepreneur.
We focus on the size of the government, on freedom from corruption and on “market freedom” defined as a cluster of variables
related to protection of property rights and regulation. We test these relationships by combining country-level institutional
indicators for 47 countries with working-age population survey data taken from the Global Entrepreneurship Monitor. Our results
indicate that entrepreneurial entry is inversely related to the size of the government, and more weakly to the extent of corruption.
A cluster of institutional indicators representing “market freedom” is only significant in some specifications. Freedom from
corruption is significantly related to entrepreneurial entry, especially when the richest countries are removed from the sample,
but unlike the size of government, the results on corruption are not confirmed by country-level fixed-effects models. 相似文献

The European COST Action E45 on European Forest Externalities (EUROFOREX) participants developed a set of good practice guidelines for the non-market valuation of forests, elaborating on stated and revealed preference methodologies, as well as benefit transfer and meta-analytical procedures. This article presents a summary of the guidelines. 相似文献
