Insuring Banks Against Liquidity Shocks: The Role of Deposit Insurance and Lending of Last Resort

Abstract.  It has long been recognized that banks' simultaneous provision of monitoring and liquidity services is advantageous but leaves them susceptible to liquidity shocks that may culminate in a system failure. Because a system failure is costly, this provides a rationale for adopting arrangements, including a lender of last resort and deposit insurance (DI), to insure banks against liquidity shocks. These arrangements have proven themselves very successful, but they have also been the source of problems. Researchers have identified some of the main sources of these problems and have suggested ways to improve the design of these arrangements, but there are still many issues that remain unaddressed. This paper reviews the literature on the two arrangements that most countries have adopted to insure banks against liquidity shocks, a lender of last resort and DI, and compares the design of these arrangements across countries. The paper ends with a brief summary of the key lessons learned about the design of these arrangements and the issues related to them that remain unaddressed.     

Did Futures Markets Stabilise US Grain Prices?

Though economists are divided over whether, in practice, futures markets reduce spot price volatility, observers of nascent nineteenth century US futures markets essentially praised the stabilising effects of this financial innovation. Indeed, such praise is understandable, particularly if, as the Chicago Board of Trade (CBOT) and others assert, “violent” spot price fluctuations were common prior to, but not after, the 1870s; the same decade that grain trade historians typically associate with the birth of the modern futures contract. And whereas these events may be unrelated, the claim is intriguing because it requires that nineteenth century futures prices fulfil their price discovery function, a property that many modern futures markets do not possess. This paper explores what role, if any, the advent of futures trading may have had on spot price volatility. I corroborate the CBOT's assertion regarding diminished spot price volatility around the 1870s and show that early futures prices did indeed fulfil their price discovery function. Moreover, I address two alternative hypotheses that relate the decline in spot price volatility to the Civil War. Ultimately, I maintain that the evolution of futures markets is the principal proximate reason why commodity spot price volatility diminished.     

Keynesian theorising during hard times: stock-flow consistent models as an unexplored 'frontier' of Keynesian macroeconomics

This paper argues that the stock-flow consistent approach tomacroeconomic modelling (SFCA) is a natural outcome of the pathtaken by Keynesian macroeconomic thought in the 1960s and 1970s,a theoretical ‘frontier’ that remained largely unexploredwith the end of Keynesian academic hegemony. It does so in twosteps. First, it phrases the representative views of Davidson,Godley, Minsky and Tobin as different ‘closures’of the same (SFC) accounting framework, calling attention totheir similarities and logical implications. Second, it discussesunresolved issues within this approach and how it differs from‘modern’ theorising.     

Debt and equity as optimal contracts

This paper shows the simultaneous optimally of debt and equity contracts in a principal-agent model. The agent (an entrepreneur) has an investment project but does not have the necessary funds to finance it. There is moral hazard in the model, generated by the dependence of the project's expected return on the (unobservable) agent's effort. Key to the optimality of these financial instruments is the nonassignable rent produced by the project and captured by the entrepreneur when the investment is successful.     

Collective entrepreneurship at Qualcomm: combining collective and entrepreneurial practices to turn employee ideas into action

Successful new products are essential to every company for survival in the marketplace. Especially discontinuous innovations are attractive because they can contribute to revenue growth by creating new businesses or addressing new market segments. Employees and their entrepreneurial spirit are often not fully utilized in a company's innovation activity. This paper presents a coherent methodology to promote corporate entrepreneurship and transform the creative thinking of many employees into valuable products. The application of this methodology at Qualcomm has resulted in more than 1,100 participants submitting almost 730 new business ideas, resulting in over $60 million in funding for several incubation and joint‐venture projects over the past four years, some of which have already produced innovations that the company values at over $300 million. Further, the paper discusses the limitations of this approach, its transferability to other companies as well as implications for future research.     

Commodity futures contracts: Furnishing an elastic currency in the nineteenth century

In this paper, I show that nineteenth century US interest rates are relatively more volatile before 1874 and I propose, and demonstrate how, commodity futures trading is the likely principal proximate explanation for this change in behavior. Borrowing from Turnovsky [Econometrica 51 (1983) 1363], I model the optimizing behaviors of risk averse producers and risk neutral speculators in the absence and presence of futures contracts and I show that, so long as one party to a futures contract was risk averse, futures markets would have quelled interest rate volatility caused by variations in planting and harvesting conditions.     

Globalization and Contemporary Banking: On the Impact of New Technology

Technological innovation has contributed to recent changes inthe conduct and character of banking, but its impact has beencontradictory. First, money-dealing transactions have becomecheaper, but investment costs have increased and a broader rangeof services had to be provided. The cost efficiency of bankshas not improved. Second, banks have developed computationallyintensive, ‘arms length’ techniques to assess creditworthinessand manage risk. Thus, they have been able to generate new revenuestreams from lending to individuals and from fees for moneymarket mediation. This shift has signalled a decline of ‘relational’banking. Third, new technology and related practices have facilitatedthe entry of foreign banks into developing countries, wherethey can exploit ‘arms length’, technologicallydemanding niches in domestic markets. This has not improvedthe efficiency of host banking systems, nor increased the availabilityof credit to the productive sector.

Viene reimpostato lo schema di valutazione delle opzioni considerando il tasso d'interesse come variabile di base del mercato e studiando il problema di valutazione del prezzo in un modello stocastico di equilibrio per la struttura a termine dei tassi d'interesse. Sono ricavate limitazioni per la funzione valore delle opzioni ed estesi al comparto obbligazionario risultati classici della teoria dell'option pricing, utilizzando proprietà di martingala vengono proposte soluzioni in forma integrale dell'equazione generale di valutazione del prezzo.     

Hedonic prices indexes for new passenger cars in Portugal (1997–2001)

This paper evaluates the effects of quality change on the price index for new passenger cars in Portugal for the years 1997–2001. Hedonic regression models are studied, giving particular emphasis to the relation between the form of the price index and the econometric techniques used for inference. The results of the empirical part of the paper indicate that during this period the changes in the quality of new cars sold in Portugal are responsible for price increases averaging 4.8% per year. Because this quality change was not entirely taken into account, in recent years the CPI component corresponding to the sales of new passenger cars may have been overestimated by as much as 2.2 percentage points per year. This corresponds to an overestimation of the overall CPI by about 0.15 percentage points per year.
