Previous findings that related diversification creates value have been called into question over concerns about methodology and measures. Reviewing existing theory to consider how a firm's knowledge base interacts with its product market activity, I address several of these concerns by creating a measure of technological diversity based on citation‐weighted patents. The measure indicates a firm's opportunity for corporate diversification based on economies of scope in valuable knowledge assets, is defined for both single‐ and multibusiness firms, and is not correlated with more fundamental aspects of diversification, such as the number of businesses in the corporate portfolio. Evidence from a large sample of firms shows the positive relationship between diversification based on technological diversity and market‐based measures of performance, controlling for R&D intensity and capital intensity as further indicators of the type of assets underlying diversification. Results hold when controlling for the endogeneity of diversification and performance in a cross‐sectional sample or when controlling for unobserved factors using panel data.

The policy environment for the Irish agri‐food sector could change rapidly in the coming decade. A potentially positive factor will be the elimination of milk quotas in 2015, although a potentially negative factor will be further trade liberalisation and increased import competition. These changes come on top of the move to decouple direct aids to farmers in 2005 as part of the Mid‐Term Review of the EU's Common Agricultural Policy agreed in 2003. This paper examines these reforms and their impacts on the Irish economy and income distribution using a CGE model particularly rich in detail on the agri‐food sectors, differentiated household groups, and agricultural policy instruments including their links to productive factors and households. The results suggest that the past and projected changes in the policy environment have, in sum, a small positive impact on GDP and household income. However, the gains and losses are unequally distributed across sectors and household groups due to the highly differentiated distribution of support and protection. Although all households generally gain from the sequence of policy reforms in the long run, some experience strong adverse effects from particular reforms and in the medium term.  相似文献

Using a sample consists of 3367 actual condominium sales transacted in resale market from May 2012 to April 2015 from the Singapore Urban and Redevelopment Authority, a hedonic pricing model is used to investigate for the presence of floor-level premiums in the private housing market, condominium, in District 23 of Singapore. Unit size, types of land tenure and the distance to the nearest mass rapid transit (MRT) station are also used as other independent variables. The estimated coefficient of each of these independent variables is statistically significant. Each of these independent variables also has positive estimated coefficient, suggesting that they have positive effects on condominium resale prices. Main findings are (a) there is a presence of floor-level premium; (b) the condominiums with a distance more than 400 m to the MRT station get higher resale prices; and (c) there is an increasing effect of floor level on condominium price.  相似文献

This paper re-examines the stochastic properties of U.S. state real per capita personal income, using new panel unit-root procedures. The new developments incorporate non-linearity, asymmetry, and cross-sectional correlation within panel-data estimation. Including nonlinearity and asymmetry finds that 43 states exhibit stationary real per capita personal income whereas including only nonlinearity produces 42 states that exhibit stationarity. Stated differently, we find that two states exhibit nonstationary real per capita personal income when considering nonlinearity, asymmetry, and cross-sectional dependence.  相似文献

We describe the quantitative modeling techniques that are used in horizontal merger review for the evaluation of unilateral effects, and discuss how the 2010 Horizontal Merger Guidelines helped legitimize these methods and motivate scholarly research. We cover markets that feature differentiated products pricing, auctions and negotiations, and homogeneous products, in turn. We also develop connections between quantitative modeling and market concentration screens that are based on the Herfindahl-Hirschman Index (HHI).

EU expansion can be seen as a positive‐sum process benefiting all countries by creating larger markets that stimulate more productive economies through increased specialization and economies of scale, implying that the general public in all countries should favour expansion. Contrarily, expansion can be perceived as zero‐sum. Capital and production relocate from higher to lower wage regions while labour does the opposite, possibly raising unemployment and reducing wages in the higher wage regions. The general public in these countries may come to oppose EU expansion attributing any deterioration in their work situation to the gains of new citizens of the European Union. Analysis of changes in Irish attitudes towards EU expansion in 2002, 2007 and 2009 finds no evidence of a link from lowered economic conditions to increased opposition to EU expansion. The only evidence for zero‐sum thinking is that diminished economic circumstances are associated with increased opposition to immigration, but this is not associated with increased opposition to further EU expansion.  相似文献

Ash emitted from the Eyjafjallajökull Icelandic volcano resulted in the closure UK’s airspace in 2010. This research highlights passengers experience throughout the crisis and it is impacted on their wellbeing. Analysis of a survey shows that just 90% of respondents highlighted the failure of airline, travel agencies and/or government to provide timely and appropriate information. The airspace closure also caused adverse health impacts, with 79% of respondents highlighting this as a concern. Although passengers were greatly inconvenienced and had a negative experience, seventy-nine percent of respondents indicated that the crisis had little or no impact on their decision to fly in the future.  相似文献

This article presents analyses of the National Assessment Program – Literacy and Numeracy (NAPLAN) data and data on other indicators that are made available through the My School website. There are large differences across states and types of schools (independent, Catholic and government) in the Year 3 NAPLAN outcomes, though the differences across states tend to diminish as outcomes for later years of study are examined. Some schools are shown to consistently have academic outcomes better than their characteristics would otherwise indicate; conversely, other schools are shown to consistently have academic outcomes below the levels their characteristics would otherwise indicate. Few of these differences are statistically significant.  相似文献
