We revisit works by Pal and Matsushima, which, respectively, present different equilibrium locations. We consider nonlinear transport costs and show that Pal's result (dispersion) is more robust than Matsushima's (partial agglomeration). Pal's result holds true for any transport cost function, while Matsushima's does not hold under strong concavity or convexity of the transport cost function. If we consider sequential move of location. Pal's result holds for any transport costs. On the other hand, Matsushima's does not hold except for linear transport cost. We also discuss welfare and show that nonlinearity of the transport cost function yields rich welfare implications. 相似文献

The present paper investigates Zhou's (1999) money search model, where money is divisible, agents can hold any amount of money and production of goods is costly, and presents a sufficient condition, expressed in terms of exogenously given parameters, for the existence of single-price equilibria. 相似文献

In this paper, we present a search model with divisible money in which there exists a continuum of monetary equilibria with strictly increasing continuous value functions and with non-discrete money holdings distributions. 相似文献

This paper studies the effects of labor supply on relative wages in a dynamic North–South model of trade. Lai (1995 )—a generalization of the Grossman and Helpman (1991a,b , ch. 11) models—showed that the relative wage of skilled (unskilled) labor in a region is positively (negatively) related to the supply of skilled (unskilled) labor in that region. These surprising results depend crucially on the specification of the functional form of the Southern imitation activity. We will show that these results (except for the relative wage of unskilled labor in Lai) are reversed in the case where the productivity of imitation depends only on the number of products the North manufactures. 相似文献

We use a mental accounting framework to study the conditions in which CEOs de‐commit to poorly performing acquisitions and so become more likely to divest them. We test this framework by contrasting the experiences of 68 firms that divested acquisitions with a control sample of 68 firms that did not divest their acquisitions. Consistent with the theory that we use to explain and predict de‐commitment, our results suggest that poorly performing acquired units tend to be divested when executives can place them within ‘attributional accounts’ (i.e., accounts for the cause of the performance that do not incriminate them) and ‘comprehensive accounts’ (i.e., within the context of overall firm performance).

The social cost of imperfect information, in terms of buyers' search costs and sellers' opportunity costs of vacancy, is estimated in the real estate market of resale condominiums in central Tokyo by using a new, comprehensive dataset of resale condominium transactions. The results suggest a substantial social cost. Specifically, if housing information were perfectly available and marketing time were null, sellers would get benefits of 22.59% of imputed net rents of their property. In addition, buyers would save 1,042,000 yen spent on search activities for one transaction, if information were perfect. This is equivalent to 13.2% of buyers' average annual income. 相似文献

A new biological nutrient removal process, anaerobic-oxic-anoxic (A/O/A) system using denitrifying polyphosphate-accumulating organisms (DNPAOs), was proposed. To attain excess sludge reduction and phosphorus recovery, the A/O/A system equipped with ozonation tank and phosphorus adsorption column was operated for 92 days, and water quality of the effluent, sludge reduction efficiency, and phosphorus recovery efficiency were evaluated. As a result, TOC, T-N and T-P removal efficiency were 85%, 70% and 85%, respectively, throughout the operating period. These slightly lower removal efficiencies than conventional anaerobic-anoxic-oxic (A/A/O) processes were due to the unexpected microbial population in this system where DNPAOs were not the dominant group but normal polyphosphate-accumulating organisms (PAOs) that could not utilize nitrate and nitrite as electron acceptor became dominant. However, it was successfully demonstrated that 34-127% of sludge reduction and around 80% of phosphorus recovery were attained. In conclusion, the A/O/A system equipped with ozonation and phosphorus adsorption systems is useful as a new advanced wastewater treatment plant (WWTP) to resolve the problems of increasing excess sludge and depleted phosphorus. 相似文献

Increased population growth and food prices have resulted in more demand for fertilizers, especially phosphorus (P), to be used in agriculture and production of food crops. Phosphorus is one of the important natural resources and will be exhausted in the near future. Nowadays, struvite production is a good method to recover P from urine. However, the natural urines contain high amounts of micro-organic pollutants which may cause health risks. Therefore, in this contribution, we investigated the amount of micro-organic pollutants in struvite from urine. There are various kinds of pharmaceuticals and hormones which are used in the world. Nevertheless, we focused on 10 pharmaceuticals (amoxycillin, carbamazepine, erythromycin, furosemide, atenolol, ibuprofen, norfloxacin, trimethoprim, tetracycline, and acetylsalicylic acid) and one hormone (17β-estradiol) as representatives. The experiments were carried out with synthetic and natural urines. After the production of struvite, the results from synthetic and natural urine samples showed that only tetracycline, erythromycin, and norfloxacin remained in the struvite, and, especially, tetracycline remained in struvite with quite a high amount. 相似文献
