Allocation of pollution abatement under learning by doing

This paper examines how learning by doing affects the allocation of pollution abatement between heterogeneous technologies over time. The optimal policy balances current abatement costs against reductions in future costs and infant technologies may be preferred to mature technologies despite greater initial costs. We characterize when a technological winner might emerge and we identify conditions under which optimal abatement is shared across all technologies. Pigouvian taxes can implement the first-best, but may need to be differentiated across technologies. When technical change is induced, an important role of environmental policies is to put abatement on the right technological trajectories.     

Italian households’ debt: the participation to the debt market and the size of the loan

This paper analyses Italian households’ participation to the debt market, separating the probability of demanding a loan from the probability of being rationed by lenders; on the supply side of the market specific attention is paid to enforcement costs of the loan contract when customers default. A new result is that the age of the household head acts essentially as a demand factor, rather than a variable influencing the lender’s choice. Both current and future households’ income increase the demand for loans and reduce credit rationing. Self-employed workers are more rationed by lenders. Credit constraints are also linked to the area where the household lives, partly because of different enforcement costs. The final part of the paper analyses the equilibrium quantity of the loan, for households who have a loan and are not constrained. The loan size is positively linked to household net wealth and income profile. An important contribution of this paper is the finding that, not only the participation to the debt market, but also the loan size is negatively affected by enforcement costs.

技术创新中路径依赖的成因及破解分析

技术创新作为一种重要的竞争策略,已经日益受到企业的重视。然而,由于路径依赖现象的存在,新技术的推广活动在市场上面临着巨大的阻力和挑战。本文通过对路径依赖产生的原因进行分析,认为正是由于转换成本和网络效应的存在导致了路径依赖的出现。转换成本的存在虽然导致了路径依赖或锁定现象的出现,但这种锁定是有限度的,在很多情况下网络效应起到了更为重要的决定作用。在网络效应的影响下,市场容易表现出正反馈的特点：如果一种技术在市场上建立起来的安装基础具有相对优势,就有可能使市场选择向有利于自己的方向发展,从而限制其它技术的市场份额。因此,一项技术创新能否取代旧技术,关键在于用户规模能否达到所需的临界容量。根据路径依赖的形成特点,本文提出了几种破解路径依赖的有效途径：大幅度提高技术水平,采取技术兼容策略和尽快达到临界容量。     

Government interventions in banking crises: effects of alternative schemes on bank lending and risk taking

We analyse the effects of policy measures to stop the fall in loan supply following a banking crisis. We apply a dynamic framework in which a debt overhang induces banks to curtail lending or choose a fragile capital structure. Government assistance conditional on new banking activities, like on new lending or on debt and equity issues, allow banks to influence the scale of assistance and externalise risks, implying overinvestment or excessive risk taking or both. Assistance without reference to new activities, like granting lump sum transfers or establishing bad banks, does not generate adverse incentives, but may have higher fiscal costs.     

Bargaining over loan contracts with signaling

This paper combines a sequential bargaining game between an enterprise and a fixed number of banks with a signaling game through which the enterprise reveals her project quality as well as her market-speed on the lending market. We characterize subgame-perfect Nash equilibrium loan contracts that are supported by separating perfect Bayesian equilibria in the signaling game. In contrast to existing models of lending markets, low-quality investment projects might be rewarded with more favorable equilibrium loan contracts than high-quality projects. Also in contrast to existing models, an increase in the competitive pressure between banks reduces the aggregate welfare in our model. The reason is that more favorable loan conditions come with a greater incentive for the ‘strong’ entrepreneur to distinguish herself from her ‘weak’ counterpart through socially wasteful signaling costs.     

Insurance,credit, and technology adoption: Field experimental evidencefrom Malawi

Does production risk suppress the demand for credit? We implemented a randomized field experiment to ask whether provision of insurance against a major source of production risk induces farmers to take out loans to adopt a new crop technology. The study sample was composed of roughly 800 maize and groundnut farmers in Malawi, where by far the dominant source of production risk is the level of rainfall. We randomly selected half of the farmers to be offered credit to purchase high-yielding hybrid maize and groundnut seeds for planting in the November 2006 crop season. The other half of farmers were offered a similar credit package, but were also required to purchase (at actuarially fair rates) a weather insurance policy that partially or fully forgave the loan in the event of poor rainfall. Surprisingly, take-up was lower by 13 percentage points among farmers offered insurance with the loan. Take-up was 33.0% for farmers who were offered the uninsured loan. There is suggestive evidence that reduced take-up of the insured loan was due to farmers already having implicit insurance from the limited liability clause in the loan contract: insured loan take-up was positively correlated with farmer education, income, and wealth, which may proxy for the individual's default costs. By contrast, take-up of the uninsured loan was uncorrelated with these farmer characteristics.     

Market Integration,Choice of Technology,and Welfare

This paper develops an international trade model where firms in a duopoly may diversify their technologies for strategic reasons. The firms face the same set of technologies given by a tradeoff between marginal costs and fixed costs, but depending on trade costs firms may choose different technologies. Market integration may induce a technological restructuring where firms either diversify their technologies or switch to a homogeneous technology. In general, market integration improves welfare. However, a small decrease of trade costs which induces a switch from heterogeneous technologies to a homogeneous technology may locally reduce global welfare. The model also shows that productivity differences lead to intra‐industry firm heterogeneity in size and exports similar to the “new–new” trade models with monopolistic competition.     

Bank behavior, incomplete interest rate pass-through, and the cost channel of monetary policy transmission

This paper employs a New Keynesian DSGE model to explore the role of banks within the cost channel of monetary policy transmission for shaping the interest rate pass-through from money market rates to loan rates. Banks extend loans to firms in an environment of monopolistic competition by setting their loan rates in a staggered way, which means that the adjustment of the aggregate loan rate to a monetary policy shock is sticky. We estimate the model for the euro area by adopting a minimum distance approach. Our findings exhibit that (i) financial costs are an important factor for price changes, (ii) frictions in the loan market have an effect on the propagation of monetary policy shocks as the pass-through from a change in money market rates to loan rates is incomplete, and (iii) the strength of the cost channel is mitigated as banks shelter firms from monetary policy shocks by smoothing loan rates.     

A Theory of Conflicts of Interest in Banking Relationships

Abstract

This paper highlights a dark side of banking relationships by elucidating the conditions under which a pre-existing relationship between a lending bank and a borrower can be detrimental to positive valuation effects of loan announcements. The effect of a pre-existing relationship is more likely to be negative when the pre-existing loans are large and firms' screening costs are low. A theoretical model shows that loan announcement's positive effect on borrowers' value due to the standard information advantage can be more than offset by the bank's conflict of interest when the bank's asset quality reputation is poor, i.e. when the probability of the bank holding a bad loan is large.     

Strategic default and optimal audit resources with costly state verification

I develop a model in which the ability to repay a loan is private information that can only be verified by the bank at some costs, which can be recovered from the borrower if it has reported untruthfully. The bank will optimize the resources it spends on this auditing of borrowers and the resulting equilibrium is then characterized. It is shown that in equilibrium, a significant fraction of companies default strategically, but most are captured via auditing. The failure rates of banks are also small. Finally extensions are discussed to include limited liability to banks and the partial recovery of auditing costs as well as punitive costs to borrowers.     

INTERNATIONAL FINANCIAL ASSISTANCE: A LOAN MECHANISM-DESIGN APPROACH

International Financial Institutions (IFIs) tie resource transfers to capital-scarce countries to improvements in their economic policies and institutions. The objective of this assistance is twofold: to augment the recipient's capital base and to improve its allocation of resources. This paper offers a political-economy explanation for the limited success of some of these loan programs. In our model, governments select policies under the influence of interest groups. Their capacity to absorb IFI loans and their reform efforts are both unobservable to the IFI. An optimally designed loan mechanism must create sufficient incentives – in the form of rewards and punishments – to counter the influence of interest groups on economic policy choices. The loan mechanism is, however, constrained in two ways: it cannot punish a country so severely as to threaten its political stability and it must remain affordable to the IFI. Whenever reform incentives are inadequate, a government will accept the loan but cheat on the implementation of reforms. If, on the other hand, the mechanism design is optimal, it might be so costly to the IFI that a well-entrenched interest group can block the reform program. Nonetheless, the availability of properly designed loan mechanisms will push governments to implement partial reforms even if the optimal mechanism is too costly for the IFI.     

Modeling technological change in energy demand forecasting: A generalized approach

Conventional economic modeling of energy demand has characterized technological choice as an investment decision driven primarily by the relationship between capital costs and operating costs. Yet the implementation of this approach has tended to yield unrealistically high estimates of the implicit discount rate governing investment decisions, particularly those involving energy efficient technologies. This result arises from incomplete specification of the process of technological choice and the diffusion of innovations. General models of diffusion include conventional costs as one set of factors among many others that influence the spread of new technologies. These more general models have been widely applied to the adoption of other new or improved products, and their use in energy demand forecasting would lead to more accurate and reliable projections. Modification of the forecasts would have policy implications. In particular, the cost of a strategy to reduce greenhouse gas emissions by encouraging more rapid diffusion of energy efficient technologies is likely to be considerably smaller than would be suggested by the conventional economic models.     

Coping with Technology Divergence Policies and Strategies for India’s Industrial Development

Recent studies on innovation have demonstrated the relationship between technology and growth. However, as most of them are centered on the experience of the highly industrialized nations, a different approach to technology policy must be taken. As late industrializers, developing countries lag in adopting foreign technologies. Institutional factors and economic policy also influence the diffusion process. With decentralized decision making, the coexistence of diverse technologies in a given industrial branch is inevitable. Consequently, social costs tend to be high because of duplication of efforts, reduced learning opportunities, and adoption of inefficient technologies. This article examines the coexistence of diverse technologies leading to technology fragmentation in India’s steel industry. Recent innovative behavior in the Japanese and Korean steel industry indicates that the effects of fragmentation can be contained through a policy of “system integration.” This is an institutional process by which industry-specific applications of scientific knowledge are fused with basic research itself. This demands a forward-looking policy that rejuvenates older industries, such as steel, in socially acceptable ways and organically creates new knowledge for national development and social welfare.     

Learning-by-doing,technology-adoption costs and wage inequality

In the dominant literature, the technological-knowledge bias that drives wage inequality is determined by the market-size channel. We develop an endogenous growth model with two technologies in which: a specific quality of labour, low or high-skilled, is combined with a specific set of quality-adjusted intermediate goods; the market-size channel is practically removed; adoption costs and learning-by-doing are linked with labour endowments. By solving transitional dynamics numerically, we show that changes in the supply of labour affect learning-by-doing and technology-adoption costs, which, in turn, influence the technological-knowledge bias and thus wage inequality. The proposed mechanisms can accommodate facts not explained by the previous literature.     

EASY MONEY OR HARD TIMES? HEALTH AND 401(k) LOANS

Rising health care costs and declining personal savings rates are nearly synonymous with household medical debt. For some, defined contribution (DC) retirement savings plans provide a ready source of funds to meet these medical debts. We examine whether health status and health insurance coverage predict the likelihood of having a DC loan using data from the Federal Reserve's triennial Survey of Consumer Finances (SCF) from 1989 to 2007. We find that poor health raises the likelihood that a household will borrow from their DC plans, even controlling for other forms of debt, access to credit, and whether households are covered by health insurance. Our estimates of the amount of the DC loan, taking selection effects into account, indicate that DC loan amounts are also influenced by health status; those with poor health borrow more from their DC plans. Apart from health status, once a household decides to borrow from their retirement funds, race and education also influence how much to borrow. We argue that public policy can improve the long‐term financial retirement security of households by offering more opportunities to save for medical emergencies, while cautiously maintaining the opportunity to borrow from DC plans.

PICKING WINNERS AND LOSERS IN THE GLOBAL TECHNOLOGY RACE

Fears that the United States is losing its leadership position in technology have prompted the Clinton administration to develop an activist policy position that supports private sector research and development activities. Tantamount to picking "winners and losers," the government, whether by mandate or by establishing a set of parameters guiding some type of competitive application process, would decide which technologies warrant future development with taxpayer supported funding. However, government subsidies designed to promote the development of new technologies often come at the expense of the diffusion of those same technologies. By limiting diffusion, these policies can impose substantial costs on society. Eliminating problems associated with current government policies and fostering the diffusion of new technologies requires limiting the assignment of property rights and restructuring the rewards associated with inventive activity. Such a system would promote the diffusion (and ultimately) the creation of new technologies. This paper proposes a forced royalty system as a potential alternate.     

An analysis of government loan guarantees and direct investment through public-private partnerships

This paper compares two forms of government support: loan guarantee and direct investment through public-private partnerships (PPPs). With loan guarantee, government provides financial guarantees to enhance project creditworthiness. With direct investment, government invests capital directly in the project. In both forms of support, the government receives shares proportional to its financial commitment. We find that loan guarantees are more effective in reducing project borrowing costs. In a perfect information environment, loan guarantee support will yield more wealth to the government than a cost equivalent direct investment. But, in an informationally asymmetric environment where the government knows less about project quality than do private partners, in other words the so-called plum problem rather than the familiar lemon problem, this implication is mitigated. We show how the portion of shares given to the government can be a bargaining tool and can mitigate information asymmetry when structuring PPPs.     

转移成本、价格歧视与银行竞争——基于霍特林模型的实证分析

在银行业竞争中,转移成本能够锁定消费者,使银行能够对锁定的消费者定一个较高的价格,但是,转移成本也使银行对没有被锁定的消费者的竞争更加激烈。研究发现,转移成本的存在增加了银行的利润,并且转移成本越高,银行从信贷中获得的利润越高。但是,当存在存款市场和贷款市场竞争时,由于价格歧视的存在,银行的利润随着转移成本的增加而降低,转移成本没有给银行带来优势。     

The effect of lender and loan type on a borrowing firm’s equity return

Past empirical studies appear to support the idea that banks and finance companies do not differ in their ability to resolve adverse selection problems associated with issuing new debt. In this article, we find there is a difference. More specifically, using an event study we find larger abnormal returns for secured loan disclosures to lower quality borrowers when the lender is a finance company versus a bank. This suggests the market views finance companies as more effective than banks in evaluating/monitoring lower quality borrowers obtaining secured loans. We posit this is due to finance companies’ greater expertise in this type of lending, resulting from specialization. Our findings extend the literature on how lender identity can influence signals about firm value from loan disclosures. Our results also support recent findings that positive abnormal returns to borrowing firms may not be a general feature across the loan population, but may be restricted to smaller, lower quality borrowers. Finally, we are the first to provide evidence that the market takes loan type into account, not just lender and borrower type, when considering the information embedded in loan disclosures.
