Inventory Control and Intermediation in Global Supply Chains
Qu, Zhan - 2015
The paper develops a simple theoretical model of inventory control in global supply chains. It identifies a role for … intermediaries in managing inventory, and shows that inserting an intermediary as an additional link in a supply chain is profitable … when demand volatility is high. It also provides conditions under which the intermediary handling inventory is located in …

Incentives Through Inventory Control in Supply Chains
Qu, Zhan - 2017
The paper shows that taking inventory control out of the hands of competitive or exclusive retailers and assigning it … because doing so solves incentive distortions that arise when retailers have to allocate inventory across sales periods, and … thus allows for better intertemporal price discrimination. Assigning inventory control to a manufacturer is also shown to …

Global Warming and Extreme Events : Rethinking the Timing and Intensity of Environmental Policy
Chen, Yu-Fu - 2010
The possibility of low-probability extreme events has reignited the debate over the optimal intensity and timing of climate policy. In this paper we therefore contribute to the literature by assessing the implications of low-probability extreme events on environmental policy in a continuous-time...

Forecasting Nonlinear Aggregates and Aggregates with Time-varying Weights
Lütkepohl, Helmut - 2010
Despite the fact that many aggregates are nonlinear functions and the aggregation weights of many macroeconomic aggregates are time-varying, much of the literature on forecasting aggregates considers the case of linear aggregates with fixed, time-invariant aggregation weights. In this study a...

Matching and Saving in Continuous Time : Theory
Bayer, Christian - 2010
We analyse optimal saving of risk-averse households when labour income stochastically jumps between two states. The generalized Keynes-Ramsey rule includes a precautionary savings term. A phase diagram analysis illustrates consumption and wealth dynamics within and between states. There is an...

Production Technologies in Stochastic Continuous Time Models
Wälde, Klaus - 2009
Properties of dynamic stochastic general equilibrium models can be revealed by either using numerical solutions or qualitative analysis. Very precise and intuition-building results are obtained by working with models which provide closed-form solutions. Closed-form solutions are known for a...

Hidden Skewness : On the Difficulty of Multiplicative Compounding Under Random Shocks
Ensthaler, Ludwig - 2014
Multiplicative growth processes that are subject to random shocks often have a skewed distribution of outcomes. In a number of incentivized laboratory experiments we show that a large majority of participants either strongly underestimate skewness or ignore it completely. Participants...

Numerical Solution of Dynamic Equilibrium Models Under Poisson Uncertainty
Posch, Olaf - 2011
We propose a simple and powerful numerical algorithm to compute the transition process in continuous-time dynamic equilibrium models with rare events. In this paper we transform the dynamic system of stochastic differential equations into a system of functional differential equations of the...

Electoral Competition with Rationally Inattentive Voters
Matějka, Filip - 2016
How do voters allocate costly attention to alternative political issues? And how does selective ignorance of voters interact with policy design by politicians? We address these questions by developing a model of electoral competition with rationally inattentive voters. Rational inattention...

On the Equivalence between Labor and Consumption Taxation
Panteghini, Paolo - 2009
This article studies the equivalence between labor and consumption taxes in a stochastic context, where the government can undertake an active portfolio management strategy by investing in both risk-free and risky assets. Using a two-period model we show that such taxes let consumers make the...
