Nonlinear Household Earnings Dynamics, Self-Insurance, and Welfare

Household Earnings and Consumption: A Nonlinear Framework

We develop a flexible framework to study the nonlinear relationship between shocks to household earnings and consumption over the life cycle. Log-earnings are the sum of a general Markovian persistent component and a transitory innovation. Consumption is modelled as an age-dependent nonlinear function of assets and the two earnings components. We establish the nonparametric identification of th...

Household Saving in LDCs : Credit Markets , Insurance and Welfare *

Some ways in which farmers in LDCs can protect their living standards against fluctuations in income are discussed. After considering the theory of consumption under uncertainty when there is no or limited borrowing, the case where some borrowing is allowed is also examined. Empirical evidence from some LDCs is used to look at (i) household borrowing and lending, their importance and timing, an...

the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...

Earnings and Consumption Dynamics: A Nonlinear Panel Data Framework∗

We develop a new quantile-based framework to study the nonlinear relationship between shocks to household earnings and consumption over the life cycle. Log-earnings are the sum of a general Markovian persistent component and a transitory innovation. Consumption is modeled as an age-dependent nonlinear function of assets and the two earnings components. We establish the nonparametric identificat...
