Equipment replacement policy: a survey

Over the past ten years there has been a considerable increase in application of theoretically correct measurement methods in determining the economic life of equipment. Approximately 89% of the firms surveyed have equipment replacement policies. The discounted rate of return method is the most widely used in determining the service life of equipment; the MAPI formula is not widely used. Difficulties in applying a replacement policy can be classified into three groups: operational, organizational, and economic. The problems mentioned most often are operational. In organizational difficulties there is usually a lack of coordination between staff and line managers. Economic problems are generally the limited funds available for equipment replacement. Formal educational programs are lacking for the development of equipment replacement managers. For the firms having replacement policies, individuals with engineering degrees are preferred over those in other disciplines for the management of the equipment replacement policy.     

Current Account, Capital Formation and Terms of Trade Shocks: a Revisit of the Harberger-Laursen-Metzler Effect

This paper extends the Blanchard model of a closed-economy to a three-good (exportable, importable and non-tradable goods) open-economy model with capital accumulation and uncertain lifetimes to study the impacts of terms of trade shocks on the current account. The simulation results show that a model with uncertain lifetimes is more appropriate to describe a small open economy like Taiwan at the steady-state equilibrium than a model with infinite lifetimes. We find that the Harberger-Laursen-Metzler effect is discernible for temporary or permanent terms of trade shocks. Furthermore, the steady state is a saddle point and the speed of convergence of capital and consumption is quite low.     

ADVERSE SELECTION IN ELECTRONIC MARKETS: EVIDENCE FROM ONLINE STAMP AUCTIONS

We analyze adverse selection costs in online stamp auctions, based on a comparison of prices on eBay with those of matched stamps at a specialty stamps auction site in the U.S., Michael Rogers, Inc. (MR), which we know a priori has low quality uncertainty. We find that buyer prices are 10–15% lower on eBay as compared to MR, and the price difference, increases with the value of the stamps. Consistent with this adverse selection discount we find that the seller reputation mechanism on eBay has an economically modest, although statistically significant, effect on auction price and probability of sale.     

ASYMPTOTICS OF IMPLIED VOLATILITY IN LOCAL VOLATILITY MODELS

Using an expansion of the transition density function of a one‐dimensional time inhomogeneous diffusion, we obtain the first‐ and second‐order terms in the short time asymptotics of European call option prices. The method described can be generalized to any order. We then use these option prices approximations to calculate the first‐ and second‐order deviation of the implied volatility from its leading value and obtain approximations which we numerically demonstrate to be highly accurate.     

Relinking Cross‐functional Collaboration,Knowledge Integration Mechanisms,and Product Innovation Performance: a Moderated Mediation Model

Previous research shows that knowledge integration mechanisms (KIMs) mediate the cross‐functional collaboration‐product innovation performance relationship; however, this mediating effect seems to be rather weak. This study, in contrast, develops a moderated mediation (MOME) model to argue that such a mediating effect is moderated by product innovativeness. A sample comprised of 106 manufacturing firms is utilized in the analyses. A moderated‐mediation approach shows that the mediating effect of KIMs in the linkage between cross‐functional collaboration and product innovation performance varies by different perspectives of product innovativeness. From an industry (macro‐level) perspective, product innovativeness positively moderates the mediating effect of KIMs on product innovation performance; in contrast, such a moderating effect is not significant under a firm (micro‐level) perspective.

Foreign direct investment and business cycle co-movements: The panel data evidence

The previous literature has largely overlooked the possible channels through which foreign direct investment (FDI) might influence business cycle synchronization. In this study we analyze the linkages that exist among FDI, trade and industrial dissimilarity in relation to business cycle co-movements using a panel data set taken from 77 pairs of developed countries. The error component three-stage least squares (EC3SLS) estimates from a simultaneous equations model with panel data are shown to be superior to the estimates obtained from single equation models or simultaneous equations models with cross-sectional data. Our results indicate that FDI serves as a channel of international business cycle transmission that is equally important as the channels of trade and monetary policy. On the contrary, industrial dissimilarity is identified as having an indirect impact on the business cycle correlation through trade and FDI. Furthermore, our findings suggest that in our sample FDI is of the horizontal type and tends to substitute for trade.     

Planned obsolescence and monopoly undersupply

This paper examines the welfare implications of planned obsolescence in situations where the traditional monopoly undersupply exists. We find that the monopolist’s introduction of incompatibility between successive generations of products alleviates the monopoly undersupply problem and may therefore generate higher social welfare than compatibility. Paradoxically, the stronger the network effects, the more likely welfare will increase as a result of incompatibility. Our result also extends to two-sided markets characterized by indirect network effects.     

Friedman meets Becker and Mulligan in a monetary neoclassical growth model

We study a neoclassical growth model with the time preference determined by resources spent on imagining future pleasures along the line of Becker and Mulligan (Q J Econ 112:729–758, 1997). We introduce money into the economy via a cash-in-advance constraint and study the effect of higher seignorage taxes or higher monetary growth rates on capital, consumption and welfare in the long run. We find that if the fraction of investment constrained by cash is smaller than a threshold, the negative-monetary-growth Friedman (The Optimum Quantity of Money and Other Essays, 1969) rule does not hold and the optimal inflation rate is positive. Calibrating our model yields a mild optimal inflation rate per annum with a switch from zero inflation to optimal inflation creating a sizable welfare gain in terms of consumption equivalence.     

Managing TFT-LCDs under uncertainty: When crystal cycles meet business cycles

Understanding the correlation between the crystal cycle and the business cycle is important, because it can help managers to anticipate change, reduce environmental uncertainty, and formulate operational objectives. To this end, we focused on China and the U.S. in our analysis. We found that the economic indicators that were the most relevant in the characterization of China's huge and burgeoning TFT-LCD market are gross domestic production and industrial production. We complemented this finding by conducting similar analyses in the U.S. market using a more comprehensive list of economic indicators.
