The impact of the presence of biased managers as strategic commitment on endogenous market structures

We consider the endogenous selection of strategic contracts in an asymmetric duopoly with substitutable goods. The market includes a biased manager, in terms of the market size the manager expects, in a managerial duopoly with separation between ownership and management. In particular, we focus on how the types of managers selected by owners affect the equilibrium market structures. Furthermore, by considering that each manager's expectation of market size depends on their own type and the type of the rival manager, we examine a situation in which the owner is less certain of the type of manager.     

R&D boundaries of the firm: An estimation of the double-hurdle model on commissioned R&D,joint R&D,and licensing in Japan

This paper studies the firm’s decisions on in-house R&D and its procurement from outside through commissioned R&D, joint R&D, and technology acquisitions (i.e., licensing-in). Using the data about 14,000 manufacturing firms in Japan, we estimate a modified double-hurdle model in which the first hurdle determines whether the firm should perform any R&D at all and the second hurdle determines whether (and how much) it should perform each mode of procured R&D. The results generally support the two major theories—the transaction cost theory and the capability theory. The estimated positive effects of firm size, in-house R&D intensity, diversification, and vertical integration support the hypothesis that capability is needed for procured R&D, while the estimated positive effect of the index of appropriability by patents supports the hypothesis that this appropriability reduces transaction costs. In addition, we found that information flow from scientific sources and that from transaction-based sources affect the three modes of procured R&D differently.     

Productivity versus elasticity: a normalized constant elasticity of substitution production function applied to historical Soviet data

This study tests the extensive growth hypothesis, which would attribute the Soviet economic slowdown to low elasticity of substitution and over-investment rather than deteriorating productivity growth. To circumvent the low availability of data, widely applicable new methods for estimating productivity and elasticity of substitution were developed based on the normalized constant elasticity of substitution (CES) production function. One is an extended version of the Solow residual calculation, and the other is a direct estimation of the time-varying parameter normalized CES production function. The application of the methods to the Soviet data showed a decreasing trend in productivity growth and a low elasticity of substitution of approximately 0.25. The results neither reject nor support the extensive growth hypothesis because of uncertainty in the interpretation of the low elasticity of substitution. The results suggest that it is reasonable to assert that both deteriorating productivity growth and low elasticity of substitution caused the Soviet economic slowdown. Further empirical studies on productivity and elasticity of substitution in the Soviet and other economies are necessary to fully understand relations between productivity growth, elasticity of substitution and economic development.     

Is living in African cities expensive?

Although several studies have examined why overall price levels are higher in richer countries, little is known about whether there is a similar relationship at the urban and city level across countries. This paper compares the price levels of cities in Sub-Saharan Africa with those of other regions by analyzing price information collected for the purpose of calculating official purchasing power parities. The approach of the paper is to readjust the calculated price levels from national to urban levels, using known price-level ratios between those areas. The results indicate that African cities are relatively more expensive, despite having lower income levels. The price levels of goods and services consumed by households are 25 to 28 percent higher in Sub-Saharan Africa than in other low- and middle-income countries, relative to their income levels. Such high costs of living could constrain livelihood of low-income urban residents, as well as the development of Africa’s urban economies.     

An Index Number Method for Estimating Scale Economies and Technical Processes Using Time-series of Cross-section Data: Sources of Total Factor Productivity Growth for Japanese Manufacturing, 1964–1988

Sample multicollinearity often makes it difficult to estimate returns to scale. We present an index number method to overcome potential multicollinearity problems when the production function is homogeneous of degree k . We apply our method to estimate empirically the effects of returns to scale and technical progress on growth in total factor productivity (TFP) using establishment data for Japanese manufacturing industries. We find that, while significant scale economies exist in many manufacturing industries, the TFP growth in the last twenty-five years is attributable primarily to technical progress. This finding also validates the current practice of assuming constant-returns-to-scale production functions in macroeconometric modelling.

Price setting in forward-looking customer markets

If consumers form habits in individual goods, firms face a time-inconsistency problem. Low prices in the future help attract customers in the present. Firms, therefore, have an incentive to promise low prices in the future, but price gouge when the future arrives. In this setting, firms benefit from “committing to a sticky price.” If consumers have incomplete information about costs and demand, the firm-preferred equilibrium has the firm price at or below a “price cap.” The model therefore provides an explanation for the simultaneous existence of a rigid regular price and frequent “sales”.     

The Impact of the Home Valuation Code of Conduct on Appraisal and Mortgage Outcomes

The accuracy of appraisals came into scrutiny during the housing crisis, and a set of policies and regulations was adopted to address the conflict‐of‐interest issues in the appraisal practices. In response to an investigation by the New York State Attorney General's office, the Home Valuation Code of Conduct (HVCC) was agreed to by Fannie Mae, Freddie Mac and the Federal Housing Finance Agency. Using unique data sets that contain both approved and nonapproved mortgage applications, this study provides an empirical examination of the impact of the HVCC on appraisal and mortgage outcomes. The results suggest that the HVCC has led to a reduction in the probability of inflated valuations, although valuations remained on average inflated, and induced a significant increase in the incidence of low appraisals. The well‐intentioned HVCC rule made it more difficult to obtain mortgages to purchase homes during the housing price crash, possibly exacerbating the fall in prices.     

Term Structure of Interest Rates Under Recursive Preferences in Continuous Time

This paper proposes a testable continuous-time term-structure model with recursive utility to investigate structural relationships between the real economy and the term structure of real and nominal interest rates. In a representative-agent model with recursive utility and mean-reverting expectations on real output growth and inflation, this paper shows that, if (1) real short-term interest rates are high during economic booms and (2) the agent is comparatively risk-averse (less risk-averse) relative to time-separable utility, then a real yield curve slopes down (slopes up, respectively). Additionally, for the comparatively risk-averse agent, if (3) expected inflation is negatively correlated with the real output and its expected growth, then a nominal yield curve can slope up, regardless of the slope of the real yield curve.
