## Title
Consumer leverage modeling

## Abstract

Embodiments of the present invention relate to systems, methods and computer program products that model consumer leverage and provide a leading indicator that predicts increases or decreases in consumer net non-collectibles. To do so, for example, the present invention determines the growth of consumers' spending and borrowing, and tracks a relationship between the value of a ratio that compares consumers' spending and borrowing and the value of the equilibrium of the ratio that compares consumers' spending and borrowing. This relationship is then applied to predict changes in consumers' ability to repay borrowed funds and consumer net non-collectibles.

## Background
FIELD
In general, embodiments of the present invention relate to systems, methods and computer program products for modeling consumer leverage and predicting consumer net non-collectibles.
BACKGROUND
A non-collectible is a declaration by a creditor, such as a credit-card issuer, that an amount of debt is unlikely to be collected. For example, credit-card issuers often make the decision to declare that an uncollected credit-card debt to be non-collectible after six months of non-payment. Net non-collectible is the gross amount of debt declared to be non-collectible, less recoveries collected from earlier non-collectibles. For example, if a credit-card holder fails to repay on its $10,000 credit-card balance, the credit-card issuer can record a $10,000 loss. However, if the credit-card issuer later collects $3,000 from the credit-card holder that is failing to repay, then the net non-collectibles on the debt is $7,000, not $10,000 as originally recorded.
In an effort to reduce non-collectibles, financial institutions often rely on economic indicators. More credit is issued to consumers when economic indicators are good. Less is issued when they are bad. Methods for developing and applying economic indicators continuously evolve and vary from institution to institution and from financial market to financial market.
Generally speaking, an economic indicator is a statistic used to analyze characteristics of a particular market. Economic indicators fall into three broad categories: lagging, coincident, and leading. Lagging indicators are economic indicators that react slowly to economic changes, and therefore provide little predictive value. Generally lagging indicators follow an event because they are historical in nature. Lagging indicators demonstrate how well a market has performed in the past. This gives economists a chance to review their predictions and make better forecasts. For example, the unemployment rate is traditionally characterized as a lagging indicator. This is because unemployment represents previous personnel decisions and, as such, always lags behind current market conditions. For example, during the mid-1990s there was a spike in consumer credit losses in the United States, despite decreasing unemployment. Profit is another exemplary lagging indicator, because profits reflect historical performances. Similarly, customer satisfaction is an economic indicator that indicates historical performance.
Coincident indicators are economic indicators that change at approximately the same time and in the same direction as the relevant market. This provides information about the current state of the market. For example, personal income, GDP, and retail sales are coincident indicators. Coincident indicators are often used to identify, after the fact, the dates of peaks and troughs in the economy or sectors of the economy.
Leading indicators are economic indicators that predict changes in the market. A leading indicator is one that changes before the market changes. Examples of leading indicators include stock prices, which often improve or worsen before a similar change in the market. Other leading indicators include the index of consumer expectations, building permits, and money supply.
Known economic indicators and methods of applying those economic indicators have yet to reliably and consistently predict changes in consumer non-collectibles. Such predictions would enable financial institutions to save billions of dollars by effectively and timely issuing and retracting credit. For example, financial institutions could issue more credit when net non-collectibles are predicted to decrease and less when net non-collectible are predicted to increase.
SUMMARY
Embodiments of the present invention relate to systems, methods and computer program products that model consumer leverage and provide a leading indicator that predicts increases or decreases in consumer net non-collectibles. To do so, for example, the present invention determines the growth of consumers' spending and borrowing, and tracks a relationship between the value of a ratio that compares consumers' spending and borrowing and the value of the equilibrium of the ratio that compares consumers' spending and borrowing. This relationship is then applied to predict changes in consumers' ability to repay borrowed funds and consumer net non-collectibles.
A brief summary of an exemplary embodiment of the present invention will now be provided. According to this exemplary embodiment, the present invention receives spending and borrowing data across a plurality of consumers. For purposes of this example, the spending data is taken across the entire United States and represents consumers' aggregated monthly spending, including, for example, expenditures on durable goods, consumer products, and services. The borrowing data, too, is taken across the entire United States but represents consumers' aggregated monthly revolving credit outstanding. Revolving credit is a type of credit that does not have a fixed number of payments, in contrast to installment credit. Revolving credit outstanding represents the value of funds drawn against revolving credit. Examples of revolving credits used by consumers include credit cards. Accordingly, for purposes of this example, borrowing data reflects amounts consumers draw against revolving credit accounts.
After receiving the spending and borrowing data, the present invention, according to this example, determines the growth rate of consumers' monthly spending and the growth rate of consumers' monthly borrowing. The present invention then normalizes a ratio that compares the growth rate of consumers' monthly borrowing and the growth rate of consumers' monthly spending. The values associated with the normalized ratio are referred to as actual values. Next, the present invention determines the best logistic equilibrium of the ratio that compares the actual growth rate of consumers' monthly borrowing and the actual growth rate of consumers' monthly spending. The values associated with the equilibrium of the ratio are referred to as equilibrium values.
Next, the present invention models consumer leverage and compares the actual values and the equilibrium values over time. If the actual values are greater than the equilibrium values, then the present invention indicates that consumer leverage is increasing, that consumers' ability to repay borrowed funds will decrease, and that consumer net non-collectibles will increase in the future. However, if the actual values are less than the equilibrium values, then the present invention indicate that consumers are deleveraging, that consumers' ability to repay borrowed funds will increase, and that consumer net non-collectibles will decrease in the future.
In some embodiments, a method is provided that comprises receiving data taken across a plurality of consumers. The data comprises a total spending amount and a total debt amount. The method further comprises using a processor to: determine a value of a ratio that compares an actual growth rate of the total debt amount and an actual growth rate of the total spending amount; determine a value of an equilibrium of the ratio that compares the actual growth rate of the total debt amount and the actual growth rate of the total spending amount; compare the value of the ratio to the value of the equilibrium of the ratio; if the processor determines that the value of the ratio is greater than the value of the equilibrium of the ratio, providing an indication that consumer leverage is increasing and providing an indication that consumer net non-collectibles will increase; and if the processor determines that the value of the ratio is less than the value of the equilibrium of the ratio, providing an indication that consumer leverage is decreasing providing an indication that consumer net non-collectibles will decrease.
In some embodiments, a system is provided that comprises a database for storing data taken from a plurality of consumer. The data comprises a total debt amount and a total spending amount. A processor is associated with the database and configured to execute an application for prediction consumer net non-collectibles. The application executed by the processor is configured to: determine a value of a ratio that compares an actual growth rate of the total debt amount and an actual growth rate of the total spending amount; determine a value of an equilibrium of the ratio that compares the actual growth rate of the total debt amount and the actual growth rate of the total spending amount; compare the value of the ratio to the value of the equilibrium of the ratio. If the value of the ratio is greater than the value of the equilibrium of the ratio, the processor is configured to provide an indication that consumer net non-collectibles will increase. If the value of the ratio is less than the value of the equilibrium of the ratio, the processor is configured to provide an indication that consumer net non-collectibles will decrease.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
Embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
For illustrative convenience, embodiments of the present invention will be described herein as being used by any institution or business or non-business entity or portion thereof to evaluate consumers' ability to repay funds withdrawn from revolving credit accounts and predict whether consumer net non-collectibles will increase or decrease in the near future. It should be appreciated, however, that other embodiments of the present invention could be applied to evaluate consumers' ability to repay other debts, such as mortgages and other installment credits with a fixed number of payments. Embodiments of the present invention evaluate consumers at a national level, using transaction data provided from government and non-government entities that collect nationwide spending data and borrowing data. The term “spending data” as used herein refers to data that indicates the value of goods and services consumed. The term “borrowing data” as used herein refers to data that indicates the value of funds consumers withdraw from revolving credit accounts.
Outputs from embodiments of the present invention can be used by financial institutions to adjust their credit risk exposure. For example, if the present invention predicts that consumers' ability to repay outstanding credit will decrease and that net non-collectibles will increase, then financial institutions can reduce their risk exposure by issuing less credit or by retracting already issued credit. Likewise, if the present invention predicts that consumers' ability to repay outstanding credit will increase and that net non-collectibles will decrease, then financial institutions can issue more credit.
FIG. 1 provides a flow diagram illustrating an exemplary process 100 for constructing and using consumer leverage model to track consumers' ability to repay debts and predict changes in consumer net non-collectibles by: receiving spending data and borrowing data from across a large number of consumers; determining a first ratio that compares equilibrium borrowing growth rates and equilibrium spending growth rates; and determining a second ratio that compares actual borrowing growth rates and actual spending growth rates.
As represented by block 102, the process 100 generally begins with receiving spending data and borrowing data. Spending data, according to some embodiments, is data that indicates the value of goods and services consumed. In an embodiment, spending data is received on a monthly basis from the Bureau of Economic Analysis, an agency of the U.S. Department of Commerce, in the form of a monthly report that outlines the month's personal consumption expenditures. The report provides the actual and imputed monthly expenditures of all households in the United States. In other words, the monthly report includes spending data that represents the value of funds spent on goods and services targeted for individual consumption. This value is referred to herein as PCE.
The borrowing data is data that indicates the value of funds consumers withdraw from revolving credit accounts. The United States Federal Reserve Board collects data that represents total amounts of consumer credit outstanding. This data includes revolving credit and non-revolving credit. Revolving credit is composed mostly of credit card loans, but also includes some lines of credit, such as checking account overdraft protection. Non-revolving credit includes automobile loans and all other loans not including in revolving credit, such as loans for education, boats, trailers, and vacations. In an embodiment, the present invention receives spending data on a monthly basis from the United States Federal Reserve Board in the form of a monthly report that provides a value that represents the total consumer revolving credit outstanding across the entire United States. This value is referred to herein as REV. REV does not include non-revolving credit outstanding. However, it should be appreciated that some embodiments of the present invention could receive and analyze non-revolving credit outstanding data and that REV could include non-revolving credit outstanding.
As represented by block 106, the process 100 further involves determining actual historical growth rates for consumer borrowing and for consumer spending. According to some embodiments, actual historical growth rates for consumer spending are determined using historical monthly PCEs, and actual historical growth rates for consumer borrowing are determined using historical monthly REVs. For example, actual historical growth rates for consumer borrowing can be determined by calculating rates of change between historical REVs, and actual historical growth rates for consumer spending can be determined by calculating rates of change between the historical PCEs.
The process 100 then involves identifying a ratio that compares the actual growth rate of consumer borrowing and the actual growth rate of consumer spending, as indicated at block 110. In some embodiments, the identified ratio that compares the actual growth rate of consumer borrowing and the actual growth rate of consumer spending is: log(REV)/log(PCE). After identifying this ratio, the process 100, as indicated by block 114, involves normalizing the ratio. Next, the process 100 involves searching for the best logistic equilibrium of the ratio, as indicated at block 118.
Referring now to FIG. 2, graph 200 provides a consumer leverage model having two curves 202, 204. Curve 202 is a smooth curve that represents the best logistic equilibrium of a ratio that compares the growth rate of consumer borrowing and consumer spending. In the illustrated embodiment, equilibrium curve 202 represents the equilibrium of log(REVt)/log(PCEt). As indicated by graph 200, curve 202 has a high, positive slope in the early to mid 1990s. However, the slope approaches zero in the mid to late 2000s. This is because creditors in the United States were really limited up until the early 1990s, but in the early to late 1990s the United States credit market went through a period of rapid growth, where spending and borrowing increased at a rapid rate. Lenders relied on credit scoring to be very aggressive. During this period the ratio of spending to borrowing increased dramatically, but this increase was okay because new borrowers were still getting absorbed and the market was still at equilibrium. However, in the 2000s, the growth matured because the credit market became saturated. This stabilized the growth rate of spending and borrowing.
Curve 204 represents the ratio that compares the growth rate for consumer borrowing and consumer spending, after the ratio has been normalized. In the illustrated embodiment, the curve 204 represents log(REVt)/log(PCEt), after normalization. The difference between the equilibrium curve 202 and the actual curve 204 at any particular time represents consumers' leverage and ability to repay debt. For example, between 1990 and 1992, the actual curve 204 was at a higher value than the equilibrium curve 202. As such, during that time, the growth in consumer borrowing exceeded the growth in consumer spending by an unsustainable rate. For example, each time consumers spent, they also borrowed. But they failed to repay the borrowed amounts before spending again. This behavior, where consumers were borrowing faster than they were spending, created pressure in the credit market.
This pressure was relieved in the middle of 1992 when the actual curve 204 dipped to values below those of the equilibrium curve 202. This relief came mostly in the form of credit card non-collectibles. During this time, credit was withdrawn from the market and, as a result, consumers were forced to spend using their income or wealth instead of credit. And because consumers were not leveraging debt to spend, growth in consumer spending exceeded growth in consumer borrowing.
As indicated in FIG. 2, curves 202 and 204 of the consumer leverage model predicted the economic downturns of the early 1990s, the early 2000s, and the late 2000s. Before each downturn, consumer spending was decreasing and borrowing was increasing. Thus, causing the actual curve 204 to rise to values above those of the equilibrium curve 202. Toward the end of each downturn, spending was still decreasing, but spending was decreasing at a slower rate than borrowing. This led to economic stabilization in each instance.
Referring now to FIG. 3, graph 300 provides two curves 302, 304. Curve 302 represents the difference between curves 202 and 204 of FIG. 2. This difference represents consumers' ability to repay debt. In other words, curve 302 represents the residual between the actual curve 204 and the equilibrium curve 202. For example, with reference to FIGS. 2 and 3, from 1990 to 1992, the actual curve 204 was above the equilibrium curve 202, and the residual curve 302 had a positive slope. On the other hand, from 1992 to 1994, the actual curve 204 was below the equilibrium curve 202, and the residual curve 302 had a negative slope.
Curve 304 represents detrended net non-collectibles, after normalization. Net non-collectibles are referred to herein as NCOs. The NCO curve 304 is constructed using NCO data that indicates the net value of uncollected funds that lenders are forced to declare non-collectable each month because consumers are unwilling or unable to repay. For example, NCO data can be obtained on a monthly basis.
As illustrated in FIG. 3, the NCO curve 304 continuously tracks the residual curve 302 with a lag time of five to twelve months. Accordingly, the present invention can use the residual curve 302 to predict the NCO curve 304 and thereby predict changes in NCOs and changes consumers' ability repay debt.
For example, when the slope of the residual curve 302 changes from positive to negative, the slope of the NCO curve 304 follows. As previously mentioned, the residual curve 302 represents the difference between the actual curve 204 and the equilibrium curve 202. When borrowing increases at a faster rate than spending, the actual curve 204 rises to values above those of the equilibrium curve 202 and thereby causes residual curve 302 to have a positive slope. This means NCOs will increase in the following months. However, when borrowing continues but spending increases such that is increasing faster than borrowing, the actual curve 204 begins dropping to values lower than those of the equilibrium curve 202 and the slope of the residual curve 302 changes from positive to negative. This means NCOs will begin to decrease in the following months.
Referring again to FIG. 1, after determining the equilibrium of the ratio that compares the actual growth rate of borrowing and the actual growth rate of spending, the process 100 involves monitoring the values of the ratio and the values of the equilibrium of the ratio, as indicated at block 122. Then, as indicated at block 126, the process 100 predicts whether NCOs will increase or decrease. For example, if, at the time of inquiry, the actual curve 204 is at a higher value than the equilibrium curve 202 and the residual curve 302 has a positive slope, then the process 100 predicts that NCOs will increase and consumers' ability to pay will decrease. However, if the actual curve 204 is at a lower value than the equilibrium curve 202 and the residual curve 302 has a negative slope, then the process 100 predicts that NCOs will decrease and consumers' ability to pay will increase.
For example, when the process 100 predicts that NCOs will increase, lenders can offer at-risk consumers lower, fixed interest rates. This alleviates some of those consumers' financial distress and thereby enables them to pay down their debt and remain financially stable. Also, for at-risk consumers whose balance has yet to reach the credit limit, the lenders can reduce credit limits. This will mitigate any future NCOs that may result from a failure to repay. Still yet, the lenders can offer credit-protection products, such as insurance, to consumers whose accounts are at risk of failure to repay. In addition to mitigating NCOs, the aforementioned prophylactic credit treatments protect customers' credit ratings. Furthermore, it should be appreciated that when the process 100 predicts that NCOs will decrease lenders can increase revenue by increasing consumers' credit lines and by issuing new revolving credit accounts.
FIG. 4 illustrates a computer-based NCO prediction system 400 in which the process 100 is implemented, according to one embodiment of the invention. As illustrated in FIG. 4, the NCO prediction system 400 generally includes a NCO prediction server 410 communicably coupled to one or more user terminals 420 and one or more administrator terminals 430 via a network 405.

The datastore 460 may include any type of computer-readable medium for storing computer-executable instructions, such as the process 100, and for storing data, such as spending data, borrowing data, and NCO data. The processor 440 is configured to execute the computer-executable instructions stored in the memory system 460 and, thereby, use the communication interface 450 to communicate information to and from the user and administrator terminals 420, 430 and store or retrieve information in the memory system 460.
