A note on estimating the divisional cost of capital for diversified companies: an empirical evaluation of heuristic-based approaches

This note provides an empirical analysis of the potential for heuristic-based approaches to derive a divisional cost of equity from a firm's total cost of capital. Since an empirical relationship between fundamental information and systematic risk has previously been shown in other studies, idiosyncratic information on risk and performance ought to serve as a good proxy to calculate divisional adjustments. Two practically used, heuristic-based approaches are tested and a significant relationship is found between one of the measures and CAPM beta. This method may offer a plausible and comparatively uncomplicated method for adjusting a firm's total cost of capital for divisional use.

Statistical properties of returns: Financial assets versus commercial real estate

This study examines the distribution of commercial real estate returns by region (east, midwest, south, and west), by property type (office, retail, R&D office, and warehouse) and in the aggregate, and compares their distributions to those of financial assets. Nominal and real returns are examined for quarterly, semiannual, and annual periods. The quarterly nominal returns on the financial assets are mostly normal with very little indication of autocorrelation. In contrast, non-normality and autocorrelation are present in most of the nominal quarterly real estate series. The non-normality is greatly reduced when semiannual or annual returns are considered or when the quarterly series are corrected for autocorrelation. The non-normality is also lower for real returns than it is for nominal returns.     

Taxes and production: The case of Pakistan

This paper investigates the effectiveness of investment incentives and corporate income taxes in influencing production and investment decisions in the Pakistani wearing apparel and leather products industries. Three tax instruments are considered: the corporate income tax (CIT), the investment tax credit (ITC), and the capital cost allowance (CCA).The results show that since there are significant capital adjustment costs, it is important to distinguish between the short, intermediate, and long-run effects associated with the tax instruments. Production decisions are relatively more responsive to changes in the ITC rate compared to changes in either CCA or CIT rates in each run. However, only in the long run for the apparel industry are the ITC and CCA rates cost effective in stimulating investment. The CIT is never cost effective. Thus targeted instruments outperform the general CIT instrument. In addition, although the incentive to invest is enhanced, there is little effect on output. Therefore, tax incentives essentially make production techniques more capital intensive.

Location,governance, and strategic determinants of japanese manufacturing investment in the united states

A firm's decision to manufacture abroad depends on location, governance, and strategic factors. Governance factors are firm-specific. In spite of this, most empirical studies of foreign direct investment (FDI) have been conducted at the industry level (making it impossible to look at firm-specific determinants), and only a handful have considered governance, location, and strategic factors simultaneously. This paper is the first large sample study of the determinants of foreign direct investment at the product and firm-level. It examines the impact of location and governance factors, and of four types of strategic interactions, on a Japanese firm's propensity to manufacture in the U.S. The results support the view that foreign direct investment is explained by location, governance, and strategic variables. Economies of scale and trade barriers encourage Japanese FDI in the U.S. The larger a Japanese firm's R & D expenditures, the greater the probability it will manufacture in the U.S., but this is not the case for advertising expenditures. Some strategic factors are also important: Japanese firms with medium domestic market shares have the highest propensity to invest in the U.S. There is evidence of follow-the-leader behavior between firms of rival enterprise groups, but none of ‘exchange-of-threat’ between American and Japanese firms. Japanese investors are also attracted by concentrated and high-growth U.S. industries.

时间竞争条件下的时间与成本关系研究

一般认为，时间的缩短必然导致成本的增加。但目前来自世界各地基于时间竞争的诸多经验表明．快速的研发和交货有利于成本的降低和利润增加。针对这两种状况的不一致性．本文通过界定时间一成本的关系曲线和时间价格弹性的概念．同时从厂商和顾客的角度．构造了时间竞争条件下的时间和成本均衡模型。该模型从理论上解释了传统上的时间和成本的权衡关系和在时间竞争条件下两者之间一致性关系：也清晰描述了采用时间竞争策略的厂商获得较大市场份额、较高利润和明显竞争优势的现象。
