Fixed and Sunk Costs Revisited

The authors attempt to clarify the concepts of, and the link between, fixed costs and sunk costs. They argue that the root for possible confusion between fixed costs and sunk costs is the inconsistency in defining the term fixed costs. They define fixed costs uniformly as the costs that are independent of the level of output and suggest that instructors refer to the part of fixed costs that are irrevocably committed as sunk costs. Under these definitions, the statement “there are no long-run fixed costs” is incorrect. Instructors should teach students that in the long run there are no sunk costs, although there may easily be fixed costs.     

Sunk Costs, Market Access, Economic Integration, and Welfare

The nature of the equilibrium that arises after economic integration is shown to depend crucially on how initial entry costs are divided along two separate dimensions: market access versus technology costs, and fixed versus sunk costs. There are three post-integration equilibrium regimes: a traditional trade theory regime which arises when both market access costs and fixed costs are small, a new trade theory regime which arises when market access costs are small but fixed costs are high, and a market access regime which arises when market access costs are high. While the first two regimes have already appeared in the literature, the third is new. The sign, magnitude, and qualitative behavior of the welfare effects of integration across all three regimes depend on the configuration of these costs.     

What explains trade costs? Institutional quality and other determinants

This paper investigates the impact of institutional quality on trade costs across 133 countries during 1995–2014. The results show that good institutional quality significantly reduces the three types of trade costs, that is, total trade costs, trade costs of agricultural goods, and trade costs of manufactured goods. Furthermore, the effect of institutional quality is significant in reducing trade costs with regard to the different trading country pairs, the different subperiods, the components of institutional quality, and the endogeneity issue. This paper contributes to the literature by confirming a significant and negative relationship between institutional quality and trade costs from a global perspective.     

Transportation Costs and US Manufacturing FDI

In empirical models of foreign direct investment (FDI), distance is most often used to proxy for transportation costs and other pure‐trade costs. Given that distance is time invariant but transportation costs are not, this approach is less than satisfactory when actual transportation costs rise and fall over time.The contribution of this work is to explicitly control for transportation costs and thereby better understand their impact on FDI. We explore the impact of shipping costs on total US FDI stocks abroad, manufacturing stocks and service stocks using measures of sea‐shipping and air‐shipping costs in a Hausman–Taylor model that controls for endogeneity and allows for time‐invariant variables such as distance. We find that transportation costs have a positive and statistically significant relationship with US total and manufacturing FDI, suggesting a substitute relationship between FDI and trade flows consistent with horizontal MNE activity. As one would expect, these costs are insignificant for service stocks.     

The role of mental health and addiction among high-cost patients: a population-based study

Aims: Previous work found that, among high-cost patients, those with a majority of mental health and addiction (MHA)-related costs (>50%) incur over 30% more costs than other high-cost patients. However, this work did not examine other high-cost patients in depth or whether they had any MHA-related costs. The objective of this analysis was to examine the role of MHA-related care among other high-cost patients.

Methods: Using administrative healthcare data from Ontario, Canada, this study selected all patients in the 90th percentile of the cost distribution in 2012. It focused primarily on two groups based on the percentage of MHA-related costs relative to total costs: (1) high-cost patients with some MHA-related costs (0%?>?and <50%) and (2) high-cost patients with no MHA-related costs (0%). We examined socio-demographic and clinical characteristics, utilization and costs for both groups, and modeled patient-level costs using appropriate regression techniques. We also compared these groups with high-cost patients with a majority of MHA-related costs (>50%).

Results: High-cost patients with some MHA-related costs incurred over 40% more costs than those without ($27,883 vs $19,702). Patients with some MHA-related costs were older, lived in poorer neighborhoods, and had higher levels of comorbidity compared to those without. After controlling for relevant variables, having any type of MHA-related utilization increased costs by $2,698. Having a diagnosis of psychosis had a large impact on costs.

Limitations: This study did not examine children and adolescents. We were only able to account for 91% of all costs incurred by the public third-party payer; addiction-related costs from community-based agencies were not available.

Conclusions: High-cost patients with MHA incur higher costs compared to those without. When considering interventions aimed at high-cost patients, policy-makers should consider their complex nature, specifically both their physical and MHA-related comorbidities.     

The Costs of Power Interruptions in Germany: A Regional and Sectoral Analysis

A high standard of security of electricity supply comes at serious electricity system costs. However, these system costs have to be balanced with the economic costs induced by an insecure supply of electricity. Following a macroeconomic approach, we analyze the economic costs imposed by potential power interruptions in Germany. Using an extensive dataset on industries and households, we estimate both Values of Lost Load and the associated hourly costs of power interruptions for different German regions and sectors. We find that interruption costs vary significantly over time, between sectors and regions. Peaking at midday on a Monday in December at 750 Mio € per hour, the average total national outage costs amount to approximately 430 Mio € per hour. A missing gigawatt hour creates average outage costs of about 7.6 Mio €.     

Who should bear the administrative costs of an emissions tax?

All environmental policies involve costs of implementation and management that are distinct from pollution sources’ abatement costs. In practice, regulators and sources usually share these administrative costs. We examine theoretically an optimal policy consisting of an emissions tax and the distribution of administrative costs between the government and regulated sources of pollution. Our focus is on the optimal distribution of administrative costs between polluters and the government and the optimal level of the emissions tax in relation to marginal pollution damage. We demonstrate how the policy variables affect aggregate equilibrium administrative costs and show that these effects are generally indeterminate, as is the effect of the distribution of administrative costs on aggregate emissions. Consequently, the optimal sharing of administrative costs and whether the optimal emissions tax is higher or lower than marginal damage depend on specific contexts.     

NON-WAGE LABOUR COSTS, POLICY UNCERTAINTY AND LABOUR DEMAND – A THEORETICAL ASSESSMENT

Labour costs in various European countries have reached a record high in recent years. The topic of non‐wage labour costs is therefore increasingly being discussed among and between the political parties because non‐wage labour costs are likely to have major negative effects on employment. We follow the real options approach, which allows us to investigate the value to a firm of waiting to adjust labour when the firm's wage and non‐wage costs are stochastic and adjustment costs are sunk. Simulation exercises show that the interaction between hiring and firing costs, non‐wage labour costs and uncertainty can have important ramifications for employment dynamics.     

The determinants and profitability of switching costs in Chinese banking

This article models the determinants of bank switching costs in China in terms of bank characteristics and non-bank variables. It also determines the contribution of switching costs to banks’ profits. Using a sample of 151 banks over the period 2003–2013 it reports a positive relationship between bank profitability and switching costs. The main result is that bank size measured by total assets has a complex relationship with switching costs. Competition between small banks creates the incentive for lock-in and increased switching costs whereas very large banks are less exercised by lock-in and switching costs.     

Market entry and trade weighted import costs

Trade weighting is a common method of aggregating trade frictions. It will understate changes in these costs when there are non‐ad valorem trade costs and quality differences. Newly traded goods enter at higher trade costs than previously traded ones. Lower import costs shift trade to low‐quality goods with higher measured trade costs. These effects are quantitatively important. U.S. import costs fall more than twice as fast as trade weighted measures from 1974 to 2004 after the impact of shifting quality and newly traded goods is accounted for. Empirical estimates that use trade weighting will underestimate the welfare impact of trade costs.     

企业会计准则实施的交易成本分析

企业实施政府发布的《企业会计准则》就其本质来说反映了政府与企业之间的契约关系。这种契约安排的交易成本包括:准则制定成本、准则培训成本、准则执行成本以及准则疑难解释成本。新会计准则中,有完善的会计准则、相对完善的会计准则以及不完善的会计准则,实施完善程度不同的会计准则,政府和企业所产生的交易成本不同。非上市企业是否选择执行新准则,将会视交易成本的大小而定。     

Estimating the weight of opportunity costs in housing consumption

Behavioural economics suggests that people tend to neglect or underweight opportunity costs. However, strong empirical evidence for the size of the underweighting appears to be largely absent from the literature. What are the weights people attach to opportunity costs relative to out-of-pocket costs? In this article, I estimate the weight of opportunity costs in probably the largest economic decision that households make: buying a house. I show that homeowners attach approximately twice as much weight to out-of-pocket costs of their housing consumption than to the opportunity costs associated with this.     

“诺思第二悖论”及其新破解

在新制度经济学家看来,制度的一个重要作用是降低作为经济运行的"摩擦力"的交易费用。理论上,交易费用会随着一国制度的进步和完善而降低。但是,据瓦利斯和诺思测算,美国自1 870年到1 970年的1 00年间总量交易费用占GNP的比例不仅没有降低,反而越来越高了。这种理论(随着制度的进步交易费用应该越来越低)与实际(测量到总量交易费用越来越高)的矛盾被称之为"诺思第二悖论"。瓦利斯和诺思测量到的总量交易费用并非交易费用的全部,表面上测量到的总量交易费用上升了,但"理论上"的总量交易费用是下降的,即是说,随着制度的进步,不仅每笔交易的交易费用下降了,理论上的总量交易费用也是下降的,所谓"诺思第二悖论"是不存在的。     

The core periphery model with asymmetric inter-regional and intra-regional trade costs

We generalize the model of Krugman (J Polit Econ 99(3):483–499, 1991) to allow for asymmetric trade costs between regions and for (asymmetric) trade costs that are internal to the regions. We find that industrial activity, in a region, is enhanced by higher costs of importing and lower costs of exporting (more precisely, by a higher ratio between the two trade costs). This suggests that countries may impose tariffs on imported goods and seek to remove the import tariffs in other countries (unilateral protectionism) in order to foster industrial activity. Industrial activity is also promoted by lower domestic internal trade costs and higher foreign internal trade costs (more precisely, by a lower ratio between the two trade costs).     

The law of one price revisited: How do goods market frictions generate large and volatile price deviations?

This paper analyzes the role of goods market frictions in accounting for the large and volatile deviations from the Law of One Price (LOP) in a framework of flexible prices. We draw a distinction between the goods market frictions that are required to consume tradable goods (e.g., distribution costs) and those that are necessary for international transactions (e.g., trade costs). We find that trade costs generate LOP deviations by introducing a no-arbitrage band, while distribution costs cause the price to deviate from the LOP by affecting the probability that trade will occur, given the band. We then conduct a Monte Carlo simulation to show that real exchange rate volatility is positively associated with trade costs, but negatively related to distribution costs. This effect depends on the interplay of trade costs and distribution costs, as they work in opposite directions when creating arbitrage opportunities.     

RISK, INFORMATIONAL ASYMMETRY AND PRODUCT LIABILITY: An Enquiry Into Conflicting Objectives

Abstract.  Risky products inflict two costs on society; the accident and the insurance costs. The expansion in the scope of product liability since the late 1970s has increased the cost of third-party liability insurance. However, the economic analysis has, traditionally, focused on only the accident costs. Some recent works suggests a strict trade-off between minimization of the accident costs and the insurance costs. In this paper, we extend the analysis by considering both types of costs. An efficiency characterization of product liability rules is provided by assuming informational asymmetry about the risk. We show that it is possible to achieve efficiency with respect to the insurance costs as well as the care levels.     

The impact of trade costs on exports: An empirical modeling

Studies, which have discussed some of the important issues concerning the measurement of trade costs, have conceded that the literature is still in the early stages of understanding and measuring what the real costs are. It is in this context, decomposing trade costs into ‘natural’ costs, ‘behind the border’ costs, ‘explicit beyond the border’ costs, and ‘implicit beyond the border’ costs, this paper suggests a method to measure the impacts of these components on changes in exports between countries in the absence of complete information on all the components of trade costs in home and partner countries. Empirical measurement has been demonstrated using 1999 and 2004 trade data from Pakistan. The results show that Pakistan's export growth between 1999 and 2004 came mainly from the reduction in both ‘explicit and implicit beyond the border’ trade costs in partner countries.

税收成本、非税成本与企业组织形式选择——基于经济模型的研究框架

基于税收考虑的企业组织形式选择也称为最优企业组织形式税务筹划,即选择某种企业组织形式寻求最有效的税务筹划决策,税收成本和非税成本是影响这种有效选择的主要因素。不考虑非税成本时,企业组织形式偏好选择经济模型主要受企业所得税税率、股权转让所得的个人所得税税率、经营所得的个人所得税税率等变量影响。非税成本中的转换成本、牺牲非税优势的成本、协调与沟通成本等也是影响经济模型的重要因素。     

国际制度的形式选择——一个基于国家间交易成本的模型

根据制度化水平的三个维度,国际制度安排的基本形式可分为非正式协议、自我实施的正式协议、一般的正式国际组织和超国家组织。那么,缔约国如何在上述国际制度安排形式之间进行选择?本文尝试从国家间交易成本的角度为这一问题提供一个解释模型。国家间交易成本包括国家间治理成本与国家间缔约成本两个部分。国家间治理成本随着制度化水平的提高而递减,国家间缔约成本随着制度化水平的提高而递增。缔约国在选择国际制度安排形式时,将在国家间治理成本与国家间缔约成本之间进行权衡。作为理性的国际行为主体,缔约国在交易收益给定的情况下,将选择使国家间交易成本最小化的国际制度安排形式。根据这一制度选择模型,本文进一步提出了分别涉及问题领域敏感性、国家同质性、透明度、资产专用性、不确定性和交易频率的六个假说。
