OPEN ARCHITECTURE AND R&D INCENTIVES

In open systems, firms give up their property rights to technologies and permit other companies to use these technologies. We ask how an incumbent's architecture choice affects social welfare by altering R&D competition among firms. More specifically, we ask whether an incumbent, by adopting an open system, can establish its socially inefficient technology as the market standard, while an entrant is developing a more efficient technology. It is shown that an incumbent has an incentive to preempt an entrant's competing technology by choosing an open system, but that the open system might result in a premature market standard.     

Guanxi,political connections and resource acquisition in Chinese publicly listed private sector firms

In this study, we examined the role of guanxi as entrepreneurs’ resource-obtaining mechanism in private sector firms, using a data-set of 184 publicly listed firms in China. We found that guanxi indeed played a positive role that helped private sector firms gain easier access to resources. We also found that guanxi exerted even a greater positive effect on private sector firms’ resource obtaining compared to entrepreneurs’ political participation, due to being the lifeblood of business conduct and social interaction in Chinese culture.     

State-owned enterprises' political capital,city administrative rank and economic resources acquisition: Empirical evidence from Chinese capital markets

This paper examines the impact of Chinese State-Owned Enterprises' (SOE) corporate political capital and the administrative rank of the city where the firm is located on their ability to acquire economic resources. The study found that the stronger the political capital owned by SOEs and the higher the administrative rank of the cities in which SOEs were located, the easier it was for them to obtain more loans and subsidies. We also found that as the city administrative rank increased, the positive effect of SOEs' political capital on economic resources acquisition also increased. When SOEs were divided into commercial competitive versus specific functional enterprises, the administrative rank of the city in which the enterprise was located played a significant positive role in obtaining economic resources for commercial competitive enterprises, while the role of their political capital played a limited role. For specific functional enterprises, their own political capital played the more significant positive role. This paper expands the research scope of corporate political connections with a new perspective.     

Product boundary,vertical competition,and the double mark‐upproblem

We develop a model in which a main product (called product A) provides a performance quality z by itself, whereas a complementary product (called product B) is useless by itself but enhances the main product's performance quality to q > z. This asymmetric complementarity gives rise to the following results. First, if z is relatively small, then firms A and B behave as if the products are symmetrically complementary with the usual double marginalization problem. Second, if z is sufficiently large, then firms A and B price their products as if they are independent. Third, over a certain range of intermediate z, no pure‐strategy Nash equilibrium exists.     

Measuring scale efficiency from a parametric hyperbolic distance function

This paper shows how scale efficiency can be measured from an arbitrary parametric hyperbolic distance function with multiple outputs and multiple inputs. It extends the methods introduced by Ray (J Product Anal 11:183–194, 1998), and Balk (J Product Anal 15:159–183, 2001) and Ray (2003) that measure scale efficiency from a single-output multi-input distance function and from a multi-output and multi-input distance function, respectively. The method developed in the present paper is different from Ray’s and Balk’s in that it allows for simultaneous contraction of inputs and expansion of outputs. Theorems applicable to an arbitrary parametric hyperbolic distance function are introduced first, and then their uses in measuring scale efficiency are illustrated with the translog functional form.     

Union wage effects in Australia: an endogenous switching approach

Using data from the Household and Labour Income Dynamics Australia (HILDA), an endogenous switching model is employed to analyse union wage effects in Australia between 2001 and 2013. An advantage of this approach is that the decision to join a union is treated as potentially endogenous, a function of the wage differential between union and non-union workers, rather than exogenous as is the case in virtually all previous Australian studies. The article finds that the decision to join a union is highly sensitive to the wage differential between union and non-union workers. The article also finds that male (female) union workers with average union characteristics earn 12% (18%) more than male (female) non-union workers with average non-union characteristics. However, a decomposition analysis finds that this difference is due to union workers having better human capital endowments than their non-union counterparts. In addition, they also receive a lower return for those endowments. These decomposition results suggest that union wage effects in Australia may be negative, rather than the small positive effects typically found in the Australian literature.     

The Effects of New Goods and Substitution on the Korean CPI as a Measure of Cost of Living

This paper estimates upper-level substitution and new-goods bias in the Korean Consumer Price Index (CPI) from the early 1990s to the mid 2000s. It has been estimated that the upper-level substitution bias in the CPI alone increased the inflation rate by 0.51 percentage points per year over the 13-year period between 1990 and 2002. The new-goods bias further increased the inflation rate by 0.17 and 0.13 percentage points per year between 1990-1995 and 1995-2000 respectively. The Chained Laspeyres index series that is based on annually-updated weights has been found to correct less than half of the upper-level substitution bias.     

Durable-Goods Monopoly with Endogenous Innovation

While selling an existing product, a durable-goods monopolist may develop a new, improved product. The firm must consider the interaction between its intertemporal pricing and research and development (R&D) decisions. The interactions show a sharp dichotomy depending on pricing regimes. When it is optimal for the firm to continue to sell the old model along with the new model, the interactions disappear. However, when it is optimal for the firm to discontinue the sale of the old model after introducing the new model, the firm will face a time-inconsistency problem in its R&D decision .     

Nonparametric quantile regression analysis of R&D-sales relationship for Korean firms

This paper applies the nonparametric quantile regression estimation procedure to the analysis of the innovation-firm size relationship using Korean manufacturing firms data. Due to the high asymmetric distribution of R&D expenditure, the mean regression does not capture properly the stylized facts of R&D behavior; hence it underestimates the sales elasticity. Comparing the parametric estimates and nonparametric estimates allows us to see that there exists a nonlinear relationship in innovative activity and sales. Dividing the data into three groups according to the sales volume, the elasticity in the medium-sized firms is the biggest for scientific firms. This result conforms that the findings of Scherer (1965) coincide with findings from Korean manufacturing firms data in the sense that R&D expenditure tends to increase faster than firm size with size up to a point and then more slowly among larger firms. For the non-scientific firms, it steadily increases showing increasing returns to scale in innovative activity in large firms.
