This paper considers an optimal life insurance for a householder subject to mortality risk. The household receives a wage income continuously, which is terminated by unexpected (premature) loss of earning power or (planned and intended) retirement, whichever happens first. In order to hedge the risk of losing income st…
Study analyzes household capital risk and poverty trapping, deriving a new function for capital deficit distribution.
The 1/3 Financial Rule helps prevent household bankruptcy through balanced spending, savings, and debt repayment.
We investigate a multi-household DSGE model in which past aggregate consumption impacts the confidence, and therefore consumption propensity, of individual households. We find that such a minimal setup is extremely rich, and leads to a variety of realistic output dynamics: high output with no crises; high output with i…
Homeownership boosts wealth and welfare compared to renting, according to new research.
Examines how extending home loan durations affects French households financially.
Study on Spanish households' investment choices in housing, deposits, and stocks.
Study optimal portfolio for households with two goals: random and fixed deadlines.
Credit expansion led to stronger household leverage cycles during the U.S. business cycle.
Investment herding can reduce household consumption, a phenomenon called crowding-out effect.
Financial planners helped preserve and increase household net financial assets during the Great Recession.
In this article we present an alternative model for the distribution of household incomes in the United States. We provide arguments from two differing perspectives which both yield the proposed income distribution curve, and then fit this curve to empirical data on household income distribution obtained from the Unite…
We describe a method to identify poor households in data-scarce countries by leveraging information contained in nationally representative household surveys. It employs standard statistical learning techniques---cross-validation and parameter regularization---which together reduce the extent to which the model is over-…
Model analyzes mortgage relief during financial hardship.
Many households in developing countries lack formal financial histories, making it difficult for firms to extend credit, and for potential borrowers to receive it. However, many of these households have mobile phones, which generate rich data about behavior. This article shows that behavioral signatures in mobile phone…
Develops a two-layer model to design mortgage assistance products.
This study analyzes how carbon pricing affects credit risk measures in a portfolio.
The study infers risk preferences from portfolio choices and measures portfolio efficiency.
A database of objects discovered in houses in the Roman city of Pompeii provides a unique view of ordinary life in an ancient city. Experts have used this collection to study the structure of Roman households, exploring the distribution and variability of tasks in architectural spaces, but such approaches are necessari…
Enhanced deep learning model forecasts household leverage series accurately.
Parametric insurance offers better risk-sharing in high-risk settings than traditional indemnity insurance.
We found a unified formula for description of the household incomes of all society classes, for instance, of those of the European Union in year 2007. This formula is a stationary solution of the threshold Fokker-Planck equation (derived from the threshold nonlinear Langevin one). The formula is more general than the w…
Study on stock portfolio concentration among Finnish households and investors.
Model shows how confidence feedback can lead to different crisis outcomes.
New method for disaggregate electricity demand forecasting at household level.
Intra-household inequality continues to remain a neglected corner despite renewed focus on income and wealth inequality. Using the LIS micro data, we present evidence that this neglect is equivalent to ignoring up to a third of total inequality. For a wide range of countries and over four decades, we show that at least…
We found a unified formula for description of the household incomes of all society classes, for instance, for the European Union in years 2005-2010. The formula is more general than well known that of Yakovenko et al. because, it satisfactorily describes not only the household incomes of low- and medium-income society …
New indicator detects financial strain through smart meter data.
New measure predicts Dutch housing market downturns.
Efficiently optimizes orthogonal and Stiefel matrices on parallel units.
The paper develops a method for forecasting power consumption at various levels of aggregation.
We study the Merton problem of optimal consumption-investment for the case of two investors sharing a final wealth. The typical example would be a husband and wife sharing a portfolio looking to optimize the expected utility of consumption and final wealth. Each agent has different utility function and discount factor.…
Modeling supply chain disruptions from climate hazards with adaptive firms.
We investigate the distribution function and the cumulative probability for Korean household incomes, i.e., the current, labor, and property incomes. For our case, the distribution functions are consistent with a power law. It is also showed that the probability density of income growth rates almost has the form of a e…
News on inflation and monetary policy impacts US household inflation expectations.
We determine the optimal amount of life insurance for a household of two wage earners. We consider the simple case of exponential utility, thereby removing wealth as a factor in buying life insurance, while retaining the relationship among life insurance, income, and the probability of dying and thus losing that income…
This paper reports on our analysis of the 2011 CAMRa Challenge dataset (Track 2) for context-aware movie recommendation systems. The train dataset comprises 4,536,891 ratings provided by 171,670 users on 23,974$ movies, as well as the household groupings of a subset of the users. The test dataset comprises 5,450 rating…
Smart grid uses deep learning to optimize household energy use.
Subsidized insurance reduces poverty by providing social benefits and lowering government costs.
One reflection suffices for orthogonal weights, reducing GPU usage.
Recent studies using data on social media and stock markets have mainly focused on predicting stock returns. Instead of predicting stock price movements, we examine the relation between Facebook data and investors' decision making in stock markets with a unique data on investors' transactions on Nokia. We find that the…
The ability to decompose a signal in an orthonormal basis (a set of orthogonal components, each normalized to have unit length) using a fast numerical procedure rests at the heart of many signal processing methods and applications. The classic examples are the Fourier and wavelet transforms that enjoy numerically effic…
HD algorithm simulates dynamics on random matrix ensembles without generating full matrices.
New method corrects bias in estimating entropic risk for better decision-making.
Model explains capital allocation and wealth distribution dynamics in a frictional economy.
Distributed estimation and learning with privacy preserved.
The Australian Government uses the means-test as a way of managing the pension budget. Changes in Age Pension policy impose difficulties in retirement modelling due to policy risk, but any major changes tend to be `grandfathered' meaning that current retirees are exempt from the new changes. In 2015, two important chan…
Dictionary learning is the task of determining a data-dependent transform that yields a sparse representation of some observed data. The dictionary learning problem is non-convex, and usually solved via computationally complex iterative algorithms. Furthermore, the resulting transforms obtained generally lack structure…
