How do a firm’s internal capabilities and external partnerships contribute to its product and process innovativeness? How do their impacts differ? Based on the theoretical framework of exploitation and exploration, we develop an integrative model linking the impact of both internal capabilities and external partnerships on product and process innovativeness. Survey responses from Taiwanese biotechnology firms indicate that research and development (R&;D), marketing, and manufacturing capabilities have different effects on product and process innovativeness. Of the four types of external partnerships, only partnerships with universities and research institutes seem to add value, whereas partnerships with suppliers, customers, and competitors do not contribute to innovativeness. Moreover, marketing capability and customer partnerships have a positive interaction effect on product innovativeness, while manufacturing capability and supplier partnerships have a positive interaction effect on process innovativeness. 相似文献

ABSTRACTThis paper offers a commentary on Hunt’s ‘Advancing marketing strategy in the marketing discipline and beyond: From promise, to neglect, to prominence, to fragment, (to promise?)’. We focus on three issues: (1) the historical origins of marketing strategy, (2) resource-advantage theory as a general theory of competition and/or a general theory of marketing and (3) the current state and future promise of doctoral training in the history of marketing thought. 相似文献

Legal disputes are often negotiated under the backdrop of an adjudicated award. While settlements are common, they are not universal. In this paper, we empirically explore how uncertainty in adjudicated awards impacts settlement negotiations. To do so, we develop an experimental design to test how increases in variance and positive skewness of the award distribution impact negotiations and settlement rates. We find increases in variance decrease settlement rates, while increases in skewness generally increases settlement rates. We also gather individual measures of risk aversion and prudence, and incorporate these measures into the analysis to test for heterogeneous treatment effects. Overall, our results suggest that highly variable adjudicated awards can contribute to the excess use of inefficient litigation, while more positively skewed awards can reduce the use of inefficient litigation. 相似文献

This paper evaluates business cycle effects of asymmetric cross‐country mortgage market developments in a monetary union. By employing a two‐country New Keynesian DSGE model with collateral constraints tied to housing values, we show that a change in institutional characteristics of mortgage markets, such as the loan‐to‐value (LTV) ratio, is an important driver of asymmetric developments in housing markets and economic activity. Our analysis suggests that the home country where credit standards are lax booms, while the rest of European Monetary Union faces a negative output gap. Overall welfare is lower if LTV ratios are higher. 相似文献

This paper investigates the effect of shifting taxes from labor income to consumption on labor supply and the distribution of income in Germany. We simulate stepwise increases in the value‐added tax (VAT) rate, which are compensated by revenue‐neutral reductions in income‐related taxes. We differentiate between the personal income tax (PIT) and social security contributions (SSC). Based on a dual data base and a microsimulation model of household labor supply behavior, we find a regressive impact of such a tax shift in the short run. When accounting for labor supply adjustments, the adverse distributional impact persists for PIT reductions, while the overall effects on inequality and progressivity become lower when payroll taxes are reduced. This is partly due to increases in aggregate labor supply, resulting from higher work incentives. 相似文献

Managers frequently attribute the news in their earnings forecasts to various economic events. Using textual analysis, we identify the economic factors underlying earnings news from press releases. We document a wide range of industry‐wide shocks and firm‐specific actions to which the earnings news in management forecasts is attributed. As expected, earnings attributions significantly affect peer firms’ price reactions to the earnings news. Specifically, earnings news attributed to industry‐wide trends or firm structural changes leads to positive information transfers but earnings news attributed to firm competitive moves triggers negative information transfers. Information transfers are much stronger when each economic factor is mentioned the first time in a given industry‐year. Further analysis reveals that the strength of information transfers varies with firm‐level rivalry within the industry (i.e., similar business strategies, market position, and level of competition). 相似文献

Using Bayesian methods, we re-examine the empirical evidence from Ben-David, Lumsdaine, and Papell (Empir Econ 28:303–319,
2003) regarding structural breaks in the long-run growth path of real output series for a number of OECD countries. Our Bayesian
framework allows the number and pattern of structural changes in trend and variance to be endogenously determined. We find
little evidence of postwar growth slowdowns across countries, and smaller output volatility for most of the developed countries
after the end of World War II. Our empirical findings are consistent with neoclassical growth models, which predict increasing
growth over the long run. The majority of the countries we analyze have grown faster in the postwar era as opposed to the
period before the first break. 相似文献

International capital flows 总被引:1,自引:0,他引:1
The surge in international asset trade since the early 1990s has lead to renewed interest in models with international portfolio choice. We develop the implications of portfolio choice for both gross and net international capital flows in the context of a simple two-country dynamic stochastic general equilibrium (DSGE) model. We focus on the time-variation in portfolio allocation following shocks, and resulting capital flows. Endogenous time-variation in expected returns and risk, which are the key determinants of portfolio choice, affect capital flows in often subtle ways. The model is consistent with a broad range of empirical evidence. An additional contribution of the paper is to overcome the technical difficulty of solving DSGE models with portfolio choice by developing a broadly applicable solution method. 相似文献

To ensure the safety of plasma-derived medicinal products, the Dutch Blood Supply Foundation (Sanquin) performs virus validation experiments. Data from these experiments are based on serial dilution assays. Regression analysis on assay data faces several problems: only a small number of data points are available, data contain censoring and are subject to sampling error. Furthermore, the process variability inherent to the experiments is not evident. In this paper we address these problems by introducing a regression model for serial dilution data and by analyzing how validation experiments and simulation techniques can help elucidate various sources of variability the experiments are subject to. These are then incorporated into the regression model. 相似文献
