Measuring Discontinuity in Binary Longitudinal Data

Whalen, Thor; Boeri, Miriam - In: Sociological Methods & Research 43 (2014) 2, pp. 248-279

dynamics and classify trajectories accordingly. Our goal here is to develop methods to gauge the discontinuity characteristics … behaviors based on the event discontinuity they manifest. We restrict ourselves here to binary event sequences, providing … trajectory types. We suggest that the innovative measures of discontinuity presented can be further developed to provide …

Optimal Control Problems with State Specific Jumps in the State Equation

Caliendo Frank N.; Guo Nick L. - In: Mathematical Economics Letters 1 (2014) 2-4, pp. 8-8

An important class of control problems in economics are those in which the state equation switches (jumps) whenever the state variable crosses a threshold. An example is a life-cycle problem in which a household faces higher rates on borrowing than on lending, and therefore the interest rate on...

Un modello di crescita discontinua dell’impresa: teoria ed evidenza empirica

Enrico D’Elia; Nascia, Leopoldo; Zeli, Alessandro - In: Rivista di Politica Economica (2014) 1, pp. 323-354

Firm’s size tipically changes through discrete leaps over time.The model of firm’s growth discussed here entails some nonstandard consequences. Firstly, profitability is not a continuous function of size, but exhibits a number of peaks. Secondly, investment increases in those firms where...

Jam formation in traffic flow on a highway with some slowdown sections

Hanaura, Hirotoshi; Nagatani, Takashi; Tanaka, Katsunori - In: Physica A: Statistical Mechanics and its Applications 374 (2007) 1, pp. 419-430

before and after the discontinuity. The dependence of jam lengths on density is derived numerically and analytically. …

Traffic states induced by slowdown sections on two-lane highway

Hanaura, Hirotoshi; Masukura, Shuichi; Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 7, pp. 1196-1206

We study the traffic states and jams occurring on a two-lane highway with a few slowdown sections. We derive the fundamental diagrams (flow-density diagrams). The fundamental diagrams on first and second lanes depend highly on the configuration of slowdown sections. The occupancy fraction of...

Safety first consumption

Sattinger, Michael - In: Journal of Economic Theory 148 (2013) 1, pp. 306-321

This paper develops a model of safety first consumption behavior in which the likelihood of survival to the next period depends on current consumption levels. Below a threshold asset level, individuals follow a decumulation path, and above that level they follow an accumulation path. Saving...

Existence of pure Nash equilibria in discontinuous and non quasiconcave games.

Bich, Philippe - Centre d'Économie de la Sorbonne, Université Paris 1 … - 2009

In a recent but well known paper, Reny has proved the existence of Nash equilibria for compact and quasiconcave games, with possibly discontinuous payoff functions. In this paper, we prove that the quasiconcavity assumption in Reny's theorem can be weakened : we introduce a measure allowing to...
