This paper examines the role of competition in British productivity performance over the period from the late-nineteenth to the early twenty-first century. A detailed review of the evidence suggests that the weakness of competition from the 1930s to the 1970s undermined productivity growth but since the 1970s stronger competition has been a key ingredient in ending relative economic decline. The productivity implications of the retreat from competition resulted in large part from interactions with idiosyncratic British institutional structures in terms of corporate governance and industrial relations. This account extends familiar insights from cliometrics both analytically and chronologically. 相似文献

This paper examines the causal effect that trade openness has on government size in small developing countries (SDCs). We use the construction of the trade cost variables based on Baltic Dry Index in primary goods as instruments of trade openness to address the endogeneity issue. We find that the increase in trade openness leads to an increase in government size: a 1 percent expansion in trade openness (trade GDP ratio) raises government consumption over GDP ratio by approximately 0.1–0.2 percentage points on average. Its quantitative significance emphasizes the importance of rethinking the costs and benefits of trade openness for SDCs. 相似文献

Private sector incentives to participate in research partnerships can be grouped roughly into two categories: cost-economizing incentives and strategic incentives. This paper summarizes the argument in two streams of thought that are often identified with these two sides: the transaction-cost/incomplete contracts approach and the strategic management approach. The paper recounts business motives to engage in research partnerships in each and points out that differentiating between more traditional economic perspectives (transaction costs, incomplete contracts) and strategic management/organizational theory perspectives (strategic networks, resource-dependent view, dynamic capabilities, knowledge-based view, organizational learning, options approach) may not be as sharp as one might suppose at first. The complementary nature of these perspectives should be encouraging for theoreticians looking for a more integrated model of collaboration. 相似文献

ABSTRACTAccurate estimation of value-at-risk (VaR) and assessment of associated uncertainty is crucial for both insurers and regulators, particularly in Europe. Existing approaches link data and VaR indirectly by first linking data to the parameter of a probability model, and then expressing VaR as a function of that parameter. This indirect approach exposes the insurer to model misspecification bias or estimation inefficiency, depending on whether the parameter is finite- or infinite-dimensional. In this paper, we link data and VaR directly via what we call a discrepancy function, and this leads naturally to a Gibbs posterior distribution for VaR that does not suffer from the aforementioned biases and inefficiencies. Asymptotic consistency and root-n concentration rate of the Gibbs posterior are established, and simulations highlight its superior finite-sample performance compared to other approaches. 相似文献

The goal of this study is to investigate the impact of earnings from vessel sales on stock prices for international listed
shipping firms. The empirical findings show that operating income from vessel sales has a higher power in explaining stock
prices than operating earnings only as a sole piece of accounting information for future profitability, investment opportunities,
and firm valuation. The testing period is from 2000 to 2009. The methodologies are those of panel cointegration and panel
causality tests. The implications are very crucial, since managers may manipulate annual earnings by such non-operating activities. 相似文献

In this paper, we explore convergence of real per capita output across the European Union (EU) countries, as well as the transitional
behavior of possible underlying factors that are responsible for any convergence or divergence pattern. The new panel convergence
methodology developed by Phillips and Sul (2007) is employed in a production function growth accounting approach and data from the Total Economy Database and the Total Economy Growth Accounting Database. The empirical findings suggest that the EU countries form two distinct convergent clubs, exhibiting considerable heterogeneity
in the underlying growth factors. These findings should help policy makers in designing appropriate growth-oriented programs
as well as in setting priorities in their implementation. 相似文献

The traditional rationale for differencing time series data is to attain stationarity. For a nearly non-stationary first-order autoregressive process—AR (1) with positive slope parameter near unity—we were led to a complementary rationale. If one suspects near non-stationarity of the AR (1) process, if the sample size is ‘small’ or ‘moderate’, and if good one-step-ahead prediction performance is the goal, then it is wise to difference the data and treat the differences as observations on a stationary AR (1) process. Estimation by Ordinary Least Squares then appears to be at least as satisfactory as nonlinear least squares. Use of differencing for an already stationary process can be motivated by Bayesian concepts: differencing can be viewed as an easy way to incorporate non-diffuse prior judgement—that the process is nearly non-stationary—into one's analysis. Random walks and near random walks are often encountered in economics. Unless one's sample size is large, the same statistical analyses apply to either. 相似文献

The purpose of this paper is to provide estimates of a disequilibrium labor market model which has been fitted to the US private non-farm sector and to the manufacturing sector. After examining the rationale of the ‘minimum’-type disequilibrium model, we reject it in favor of a formulation suggested by Chow. The latter provides not only a wage adjustment mechanism, but also a quantity adjustment mechanism and treats wages and quantities symmetrically. The empirical findings for both sectors support the disequilibrium formulation employed and reject the equilibrium hypothesis for the labor market. 相似文献
