Ebook Learning in the Credit Card Market

Sat, 07 Nov 2009 08:04:33 +0000

Economists believe that learning through experience underpins optimization and generates technological progress. Large literatures measure learning dynamics in the lab, and in the field.

However, because of data limitations, relatively few papers measure learning in the field with micro-level (household) panel data. Among such household studies, most show that households learn to optimize over time. For example, Miravete (2003) and Agarwal, Chomsisengphet, Liu and Souleles (2007) respectively show that consumers switch telephone calling plans and credit card contracts to minimize monthly bill payments.

PDF Ebook Advanced Driver Assistance Systems Information Management and Presentation

Sat, 07 Nov 2009 07:43:57 +0000

With the development of advanced driving assistance systems, in-vehicle communication and information systems, there are situations where the driver becomes overloaded by information, creating potentially dangerous conditions. In this Thesis a novel strategy is proposed, to prioritise and present information.

Firstly two main criteria are extracted, that allow the ability to rank messages: the risk associated with the non-presentation of the message, and its relevance to the environment. Fuzzy cognitive maps enable to represent expert knowledge and model these relationships.

PDF Ebook Prevention and Treatment of Diabetes with Natural Therapeutics

Sat, 07 Nov 2009 05:56:09 +0000

Diabetes Mellitus (DM) is a group of diseases, all of which are characterized by elevated blood sugar levels. In the United States it is estimated that over 20 million people have one form of diabetes or another1. There are many different forms of the disease, each caused by different factors. Some causes of diabetes are still unknown. Diabetes is concerning because high blood sugar causes damage to many parts of the body, including blood vessels, heart, eyes, kidneys and nerves. This damage can lead to kidney failure, requiring transplant or dialysis, heart attacks, heart failure and stroke.

There are a few key words and concepts helpful in understanding diabetes, the problems, or “complications” occurring with the disease and the potential benefits of various types of treatment. The section below “Definitions and Concepts” should help guide you through the remainder of this resource. We hope this report helps you to understand diabetes better, and helps outline some of the pros and cons of different treatments.

Ebook Interim Report Of The Committee On Capital Markets Regulation

Sat, 07 Nov 2009 04:25:27 +0000

The United States has for many years been recognized as having the largest, most liquid, and most competitive public equity capital markets in the world. These well functioning capital markets play a vital role in our economy. For years, established American companies, the dominant users of these markets, have raised capital on better terms—rates up to one percent lower, according to academic estimates. U.S. investors across the country have the opportunity to invest in familiar home markets with the prospect of higher profits. Not surprisingly, there is considerable evidence that countries with better financial markets, like the United States, enjoy more rapid economic growth, which creates more new jobs nationwide. The U.S. legal and regulatory regimes that promote accountability, disclosure, and transparency are an important element in the success of U.S. capital markets.

The venture capital industry is a particular beneficiary of the large, deep U.S. capital markets. Venture capitalists, who identify and incubate so many of the innovative start-up firms, can more easily and profitably sell their maturing investments in order to obtain funds for reinvestment into new start-ups. The growing, smaller firms these venture investors identify are important sources of new jobs: about 40 percent of all employment in publicly traded companies is in firms launched by venture capitalists.

The financial services industry across the country is the home of an important share of high-paying, attractive U.S. jobs. This industry contains 5 percent of private sector jobs but produces 8.1 percent of GDP. The securities industry, including the stock markets, while relatively small, provides even better paying jobs nationwide: although it contains only 0.65 percent of private-sector employment, it is responsible for 1.4 percent of GDP.

Ebook Financial Market Development and the Importance of Internal Capital Markets: Evidence from International Data

Sat, 07 Nov 2009 03:54:29 +0000

Internal capital is a major source of funds for financing corporate investments. For example, Lamont (1997) estimates that for the 1981-1991 period, internal funds accounted for more than three quarters of capital expenditure outlays for U.S. non-financial corporations. This reliance on self-generated cash as a source of investment funds has prompted researchers to investigate the relationship between firms‘ investment decisions and internal resources. In a world where capital markets are perfect and all firms have free access to external sources of financing, investment decisions would be based solely on expected future profitability and, thus, not be affected by the availability of internally generated funds. In the real world, however, capital market imperfections exist, making internal funds less costly and therefore more attractive than external funds. This reliance on internal funds should be stronger for firms facing greater capital market imperfections, i.e., firms in countries where external capital markets are less developed. The interesting empirical question that arises therefore is whether corporate investments are indeed more sensitive to the availability of internal funds for firms in less developed economies. This is the question this paper addresses. In recent years, there have been several studies examining cross-country differences in the development of financial markets and its impact on economic growth (La Porta, Lopez de Silanes, Shleifer, and Vishny (1997, 1998), Levine and Zervos (1998), Rajan and Zingales (1998), Beck, Levine, and Loayza (2000)). Starting with the seminal work of Fazzari, Hubbard,and Petersen (1988), there is also a large literature on the impact of external financing constraints on the sensitivity of investments to internal cash in a variety of domestic contexts (see, e.g., Fazzari, Hubbard, and Petersen (1988, 2000), Blanchard, Lopez-de-Silanes, and Shleifer (1994), Calem and Rizzo (1995), Gilchrist and Himmelberg (1995), Kaplan and Zingales (1997, 2000), Cleary (1999), Erickson and Whited (2000), and Houston and James (2001)).1 In view of the fact that current cash flow is likely to be positively correlated with future profitability/growth opportunities, these studies have typically used Tobin‘s q as an independent variable to control for it. While the domestic evidence on the impact of internal cash on investments is extensive, the international evidence is surprisingly sparse. Even the limited evidence that exists is mixed in nature. On the one hand, Hoshi, Kashyap, and Scharfstein (1991) and Shin and Park (1998) find that the sensitivity of investments to internal cash flow is less for Japanese and Korean firms that belong to corporate groups and thus have easier access to external capital. Similarly, Schaller (1993) finds the sensitivity to be lower for Canadian firms that are older and have more dispersed ownership. On the other hand, Kadapakkam, Kumar, and Riddick (1998) and Cleary (2001) find that in several developed countries, the sensitivity is lower for smaller and financially more constrained firms, i.e., firms for which external capital market frictions are likely to be greater. None of these studies examines the variation of investment-cash flow sensitivity across countries, however. Using cash stock as a measure of internal resources, and sales as a proxy for the marginal productivity of capital, Love (2000) finds the sensitivity to be greater for less developed countries. In a somewhat different context, Wurgler (2000) examines industry-level data and finds that investment is more sensitive to value added in countries with better developed financial markets, but is unable to distinguish between the effects of future profitability and current cash flow due to data limitations in the non-U.S. portions of his sample, which preclude measuring Tobin‘s q at the industry level.

Ebook Credit Cards Scoring With Quadratic Utility Function

Sat, 07 Nov 2009 03:35:12 +0000

In this paper, we consider a general approach for classifying objects and explain it with credit cards scoring problem. Classification can be defined by a classification function assigning to each object some categorical value called the class number. However, this classification function has a very inconvenient property it is discontinuous (impossible to use it for classifying new objects). We reduce the classification problem to evaluating a continuous utility function from some general class of functions. This function is used for separating objects belonging to different sets. Values of utility functions for objects from one class should be in the same range. “The best” utility function in some class is found by minimizing the error of misclassification.

Depending upon the class of utility function, it may be a quite difficult problem from optimization point of view. However, if one is looking for a utility function, which is a linear combination of some other functions (possibly nonlinear in indicator variables), it can be formulated as a linear programming problem. Mangasarian, et al. (1995) used this approach for failure discriminant analysis with linear utility functions (applications to breast cancer diagnosis). This function is linear in control parameters and indicator variables. Zopounidis, et al. (1997, 1998), Pardalos, et al. (1997) used a linear utility function for trichotomous classifications of credit card applications. Konno, et al. (2000a, 2000b) considered utility functions which are quadratic in indicator prameters and linear in control variables.

Ebook Do Property Titles Increase Credit Access Among the Urban Poor? Evidence from a Nationwide Titling Program

Sat, 07 Nov 2009 03:17:25 +0000

A large body of work has documented extensive credit rationing in developing countries in which low-income households are excluded from the formal banking sector. A critical barrier to access is the frequent inability of small and informal borrowers to securitize loans with collateral, often a necessary condition for participation in formal credit markets. One frequently cited contributing factor is the fact that in much of the developing world a large percentage of both rural and urban property is untitled (Holden, 1997). Although land is an advantageous form of collateral due to the fact that it cannot be removed and does not easily devalue, it is widely believed that many borrowers face barriers securing transactions with land simply because ownership rights are not formally documented.

Consistent with this notion, government land titling programs are widely considered a critical instrument for increasing access to credit among the poor, and wide scale land-titling has become a popular policy prescription for alleviating credit rationing in developing countries (Binswanger, et al., 1999). However, despite the widespread use of land collateral in loan transactions in developed countries, the ability of property titles to transform modest landholdings into a viable form of collateral for commercial loans can not be taken for granted. In particular, the use of property titles to securitize loans may fail in many impoverished settings where transaction costs associated with collateral processing, foreclosure and resale are large relative to the average size of loan requests. Such costs are particularly high when political or legal factors impede repossession of property as is the case in many developing countries. Even when foreclosure is feasible, there is often a high degree of mistrust among lenders as to the validity of ownership documents, and the cost of verification may remain prohibitively high even in the context of a formal property system. If poor households are “transaction-cost rationed” in formal credit markets, the lower default risk brought about by the provision of titled property as collateral may be insufficient to facilitate access to loans. Indeed, past research has found the impact of rural titling programs on both credit supply and investment demand to be strongly size differentiated, such that small producers remain rationed out of the credit market even with a title.
