    Carbon-carbon piston development

    A new piston concept, made of carbon-carbon refractory-composite material, has been developed that overcomes a number of the shortcomings of aluminum pistons. Carbon-carbon material, developed in the early 1960's, is lighter in weight than aluminum, has higher strength and stiffness than aluminum and maintains these properties at temperatures over 2500 F. In addition, carbon-carbon material has a low coefficient of thermal expansion and excellent resistance to thermal shock. An effort, called the Advanced Carbon-Carbon Piston Program was started in 1986 to develop and test carbon-carbon pistons for use in spark ignition engines. The carbon-carbon pistons were designed to be replacements for existing aluminum pistons, using standard piston pin assemblies and using standard rings. Carbon-carbon pistons can potentially enable engines to be more reliable, more efficient and have greater power output. By utilizing the unique characteristics of carbon-carbon material a piston can: (1) have greater resistance to structural damage caused by overheating, lean air-fuel mixture conditions and detonation; (2) be designed to be lighter than an aluminum piston thus, reducing the reciprocating mass of an engine, and (3) be operated in a higher combustion temperature environment without failure

    On the Market Discipline of Informationally-Opaque Firms: Evidence from Bank Borrowers in the Federal Funds Market

    Using plausibly exogenous variation in demand for federal funds created by daily shocks to reserve balances, we identify the supply curve facing a bank borrower in the interbank market and study how access to overnight credit is affected by changes in public and private measures of borrower creditworthiness. Although there is evidence that lenders respond to adverse changes in public information about credit quality by restricting access to the market in a fashion consistent with market discipline, there is also evidence that borrowers respond to adverse changes in private information about credit quality by increasing leverage so as to offset the future impact on earnings. While the responsiveness of investors to public information is comforting, we document evidence that suggests that banks are able to manage the real information content of these disclosures. In particular, public measures of loan portfolio performance have information about future loan charge-offs, but only in quarters when the bank is examined by supervisors. However, the loan supply curve is not any more sensitive to public disclosures about nonperforming loans in an exam quarter, suggesting that investors are unaware of this information management

    Why do banks promise to pay par on demand?

    We survey the theories of why banks promise to pay par on demand and examine evidence about the conditions under which banks have promised to pay the par value of deposits and banknotes on demand when holding only fractional reserves. The theoretical literature can be broadly divided into four strands: liquidity provision, asymmetric information, legal restrictions, and a medium of exchange. We assume that it is not zero cost to make a promise to redeem a liability at par value on demand. If so, then the conditions in the theories that result in par redemption are possible explanations of why banks promise to pay par on demand. If the explanation based on customers’ demand for liquidity is correct, payment of deposits at par will be promised when banks hold assets that are illiquid in the short run. If the asymmetric-information explanation based on the difficulty of valuing assets is correct, the marketability of banks’ assets determines whether banks promise to pay par. If the legal restrictions explanation of par redemption is correct, banks will not promise to pay par if they are not required to do so. If the transaction explanation is correct, banks will promise to pay par value only if the deposits are used in transactions. After the survey of the theoretical literature, we examine the history of banking in several countries in different eras: fourth-century Athens, medieval Italy, Japan, and free banking and money market mutual funds in the United States. We find that all of the theories can explain some of the observed banking arrangements, and none explain all of them

    Market Failures and Regulatory Failures: Lessons from Past and Present Financial Crises

    Full text link
    The paper analyzes the financial crisis of through the lens of market failures and regulatory failures. We present a case that there were four primary failures contributing to the crisis: excessive risk-taking in the financial sector due to mispriced government guarantees; regulatory focus on individual institution risk rather than systemic risk; opacity of positions in financial derivatives that produced externalities from individual firm failures; and runs on the unregulated banking sector that eventually threatened to bring down the entire financial sector. In emphasizing the role of regulatory failures, we provide a description of regulatory evolution in response to the panic of 1907 and the Great Depression, why the regulation put in place then was successful in addressing market failures, but how, over time, especially around the resolutions of Continental Illinois, Savings and Loans crisis and Long-Term Capital Management, expectations of too-big-to-fail status got anchored. We propose specific reforms to address the four market and regulatory failures we identify, and we conclude with some lessons for emerging markets

    The Political Economy of Shadow Banking: Debt, Finance, and Distributive Politics Under a Kalecki-Goodwin-Minsky SFC Framework

    Full text link
    This paper describes the political economy of shadow banking and how it relates to the dramatic institutional changes experienced by global capitalism over past 100 years. We suggest that the dynamics of shadow banking rest on the distributive tension between workers and firms. Politics wedge the operation of the shadow financial system as government policy internalizes, guides, and participates in dealings mediated by financial intermediaries. We propose a broad theoretical overview to formalize a stock-flow consistent (SFC) political economy model of shadow banking (stylized around the operation of money market mutual funds, or MMMFs). Preliminary simulations suggest that distributive dynamics indeed drive and provide a nest for the dynamics of shadow banking

    Capital Constraints, Counterparty Risk, and Deviations from Covered Interest Rate Parity

    Full text link
    We provide robust evidence of deviations from the covered interest rate parity (CIP) relation since the onset of the financial crisis in August 2007. The CIP deviations exist with respect to several different dollar-denominated interest rates and exchange rate pairings of the dollar vis-à-vis other currencies. The results show that our proxies for margin conditions and for the cost of capital are significant determinants of the CIP deviations. Following the bankruptcy of Lehman Brothers, uncertainty about counterparty risk became a significant determinant of CIP deviations. The supply of dollars by the Federal Reserve to foreign central banks via reciprocal currency arrangements (swap lines) reduced CIP deviations. In particular, the announcement on October 13, 2008, that the swap lines would become unlimited reduced CIP deviations substantially. These results indicate a breakdown of arbitrage transactions in the international capital markets during the crisis that stems partly from lack of funding and partly from heightened counterparty credit risk. Central bank interventions helped reduce the funding liquidity risk of global institutions
