An empirical investigation of the roles of prior knowledge and learning activities in technology transfer

This study analyzes 120 university–industry technology transfer projects. A significant positive relationship was found between the learning activities performed by the firm during the development and implementation stages of the technology transfer project and the benefits to that firm from the project. In contrast, prior knowledge of the firm about the existing technology was found to have only a marginal contribution to the project benefits. However, further exploratory analysis based on high and low levels of technical and organizational uncertainty revealed more provocative relationships.

Are some taxes different than others? An empirical investigation of the effects of tax policy in Canada

This paper investigates the response of major macroeconomic variables to four different types of tax policy innovations in Canada within a VAR framework. The positive tax multipliers documented in the previous literature are found only for corporate tax innovations. Our results indicate that different taxes affect output differently, and imply that the composition of total taxes may be a major factor behind cross-country variation in the sign and magnitude of total tax multipliers.

产业关联视角下的碳关税征收对我国产业经济的影响

最终需求的生产诱发系数和依存度系数揭示,我国高耗能产业部门生产对出口依赖程度较高;碳关税征收在减少高耗能产品出口的同时,由于其产业影响力较大,会对其它产业部门的生产产生较大的波及。高耗能产业部门的感应度系数表明,当各个部门的最终需求变化时,其生产将受到较大的影响。碳关税对高耗能产品的征收最终会通过产业间的关联波及各个产业部门,进而全面影响我国产业经济的发展。     

Macroeconomic implications of modeling the Internal Revenue Code in a heterogeneous-agent framework

Tax policy analysis in heterogeneous-agent models typically involves the use of smooth tax functions to approximate complex present tax law and proposed reforms. In this paper, we explore the extent to which the tax detail omitted under this conventional approach has macroeconomic implications relevant for policy analysis. To do this, we develop an alternative approach by embedding an internal tax calculator into a large-scale overlapping generations model that, while conditioning on idiosyncratic household characteristics, explicitly models key provisions in the Internal Revenue Code applied to labor income. We find that for a debt-constant steady state analysis of a given tax policy change, both approaches generate similar policy-induced patterns of macroeconomic activity despite variation in the underlying patterns of household tax-preferred consumption and labor supply behavior. However, this variation in underlying behavior is associated with significant quantitative and qualitative differences in macroeconomic aggregates along a debt-financed transition path immediately following a policy change. Consequentially, although the use of unconditional smooth tax functions may be a reasonable modeling simplification for steady state analysis of tax policy, caution should be taken for their use in transition path analysis within heterogeneous-agent models.     

Excise taxes,over-shifting,cross-elasticity,and tax revenue

This article examines cross-elasticity effects in excise taxation for markets characterized by monopolistic competition and over-shifting. Extending the constant elasticity demand model to consider cross-elasticity leads to notably different results regarding tax revenue maximization. With nonzero but weak cross-elasticity effects relative to the price elasticity, we derive a higher optimal tax-price ratio compared to prior research. With strong cross-elasticity, revenue can continually be increased by raising the excise tax. Overall, the study offers government greater incentive to use excise taxes to obtain revenue.     

Can investors of Chinese energy stocks benefit from diversification into commodity futures?

We attempt to evaluate the diversification potential of commodity futures for energy stocks in China. With a variety of copula functions and three risk-based dynamic measures, our results show that even though commodity futures are not helpful in improving the risk-adjusted returns of energy stocks, they can significantly reduce the volatilities and expected-shortfalls of the diversified portfolios. Such diversification benefits are much larger during large market downturns than during normal times. In particular, gold (copper) futures are the most (least) attractive in diversifying risks of energy stocks in most cases. The results also highlight that the non-linear dependence cannot be ignored when estimating the diversification benefits, and more various risk hedging strategies are expected for investors holding energy stocks, especially coal company stocks.
