“主体-技术”协同视角下的战略性新兴产业创新网络分类研究——以新能源汽车产业为例

本文以“主体-技术”协同视角来分析战略性新兴产业创新网络形成的内在机理和分类模式。在结合2-模网络理论基础上,从核心技术和创新主体两个维度出发,将战略性新兴产业创新网络分为单核心实验室型、单核心产业链型、单核心辅助型、单核心复合型、多核心实验室型、多核心产业链型、多核心辅助型和多核心复合型。同时,以中国新能源汽车产业为例,通过实证分析发现：除了单核心辅助型和多核心辅助型之外,其它6种模式均存在,并进一步对其创新网络的分类模式及相关特征进行了全面分析。     

When quality signals talk: Evidence from the Turin hotel industry

This study analyzes the relationship between quality signals and price setting through the application of hedonic price functions. The model proposals also include variables relating to land use policies and tourism development strategies. A simultaneous equation model endogenously estimates quality signals. This method is appropriate for analyzing emerging urban destinations, as characterized by the presence of an expanding hotel industry. The results are based on a dataset of 145 hotels in Turin, Italy. The empirical findings reveal that reputation-based quality signals help explain tariff levels. Price proposals also include a premium for quality assured hotels, defining some limits of the current hotel classification system. The empirical evidence has significant marketing implications for the hospitality industry’s competitiveness, since the results clarify the impact of quality signals on price level.     

Expropriation risk and discounting

This paper focuses on time preference and individual measures of expropriation risk. We use survey data on Italian households and on the 50+ population in eleven European countries. The surveys provide measures of discount rate and proxies for expropriation due to criminal offenses. We show that impatience increases with expropriation risk.     

TAX‐LIMITED REACTION FUNCTIONS

This paper models for the first time a spatial process in local tax policies in the presence of centrally imposed fiscal limitations. Focusing on the frequently encountered case of a tax rate cap, we evaluate three empirical approaches to the analysis of spatially dependent limited tax policies: (i) a Bayesian spatial approach for censored dependent variables; (ii) a Tobit corner solution model augmented with a spatial lag; (iii) a spatial discrete hazard model. The evidence arising from an investigation of severely state‐constrained local vehicle taxes in Italy suggests that ignoring tax limitations can lead to substantial underestimation of inter‐jurisdictional fiscal interaction.

Lobbying for Education in a Two‐Sector Model

Firms specialized in two different sectors lobby to induce the government to subsidize the type of education complementary to their production. Lobbying is endogenous. We show that, if lobbying is not costly, both sectors will lobby in equilibrium and the education policy will induce the same skill composition that would be chosen by the social planner. However, if lobbying is costly and there is sufficient asymmetry between the sectors, only one sector will exert pressure on the policy‐maker in the attempt to direct resources toward the type of education required by its production. Which sector will engage in lobbying depends on relative size, productivity, and price. We also provide some preliminary evidence that lobbying activity by firms may influence the production of skills needed by those firms.     

Euro vs Dollar: An Improbable Threat

Ever since the setting up of the EMU, many scholars have argued that the Euro will take its place alongside the dollar and perhaps even replace it as international money. The theory behind this point of view is represented by search-theoretic models. The fundamental shortcoming of the traditional version of these models is that they fail to make a distinction between different types of money, in particular between commodity money and fiduciary money. In the international context a fiduciary money can be accepted only when a political exchange is possible between a leading country which has an interest in producing trust in the future value of its currency and other countries which attach no importance to the relative gains the issuing country acquires by exploiting the privilege of seigniorage. The Bretton Woods system and the dollar standard, although based on fiduciary monies, have worked thanks to the institutional framework maintained by the United States and accepted by other countries. Unlike the United States, the euro area is not in a position to exercise any form of political leadership on the international scene. As things stand the euro does not represent a threat to the dollar and it is bound to remain a regional money.     

递延所得税项目、条件稳健性与非条件稳健性

以所得税会计准则的执行以及企业所得税改革为背景,从条件稳健性与非条件稳健性两方面考察了中国上市公司2007～2010年递延所得税项目对会计稳健性的影响,证明了递延所得税资产和递延所得税收益(费用)既导致了非条件稳健性,又导致了条件稳健性；而递延所得税负债引起了条件稳健性,在非条件稳健性方面,不但没有表现出稳健性,反而表现出一定的激进性,说明企业在对递延所得税负债的确认上,不但没有高估负债,反而可能低估负债.     

Identification of monetary policy in SVAR models: a data-oriented perspective

In the literature using short-run timing restrictions to identify monetary policy shocks in vector-auto-regressions (VAR) there is a debate on whether (i) contemporaneous real activity and prices or (ii) only data typically observed with high frequency should be assumed to be in the information set of the central bank when the interest rate decision is taken. This paper applies graphical modeling theory, a data-based tool, in a small-scale VAR of the US economy to shed light on this issue. Results corroborate the second type of assumption.
