The book offers an overview of credit risk modeling and management. A three-step approach is adopted with the contents, after introducing the essential concepts of both mathematics and finance.Initially the focus is on the modeling of credit risk parameters mainly at the level of individual debtor and transaction, after which the book delves into counterparty credit risk, thus providing the link between credit and market risks. The second part is aimed at the portfolio level when multiple loans are pooled and default correlation becomes an important factor to consider and model. In this respect, the book explains how copulas help in modeling. The final stage is the macro perspective when the combination of credit risks related to financial institutions produces systemic risk and affects overall financial stability.The entire approach is two-dimensional as well. First, all modeling steps have replicable programming codes both in R and Matlab. In this way, the reader can experience the impact of changing the default probabilities of a given borrower or the weights of a sector. Second, at each stage, the book discusses the regulatory environment. This is because, at times, regulation can have stricter constraints than the outcome of internal models. In summary, the book guides the reader in modeling and managing credit risk by providing both the theoretical framework and the empirical tools necessary for a modern finance professional. In this sense, the book is aimed at a wide audience in all fields of study: from quants who want to engage in finance to economists who want to learn about coding and modern financial engineering.

The general store in late-nineteenth-century America was often the economic heart of a small town. Merchants sold goods necessary for residents' daily survival and extended credit to many of their customers; cash-poor farmers relied on merchants for their economic well-being just as the retailers needed customers to purchase their wares. But there was more to this mutual dependence than economics. Store owners often helped found churches and other institutions, and they and their customers worshiped together, sent their children to the same schools, and in times of crisis, came to one another's assistance.

For this social and cultural history, Linda English combed store account ledgers from the 1870s and 1880s and found in them the experiences of thousands of people in Texas and Indian Territory. Particularly revealing are her insights into the everyday lives of women, immigrants, and ethnic and racial minorities, especially African Americans and American Indians.

A store's ledger entries yield a wealth of detail about its proprietor, customers, and merchandise. As a local gathering place, the general store witnessed many aspects of residents' daily lives--many of them recorded, if hastily, in account books. In a small community with only one store, the clientele would include white, black, and Indian shoppers and, in some locales, Mexican American and other immigrants. Flour, coffee, salt, potatoes, tobacco, domestic fabrics, and other staples typified most purchases, but occasional luxury items reflected the buyer's desire for refinement and upward mobility. Recognizing that townspeople often accessed the wider world through the general store, English also traces the impact of national concerns on remote rural areas--including Reconstruction, race relations, women's rights, and temperance campaigns.

In describing the social status of store owners and their economic and political roles in both small agricultural communities and larger towns, English fleshes out the fascinating history of daily life in Indian Territory and Texas in a time of transition.
