Globalization, economic growth, and innovation: A two-country two-period model

Cuong Le Van, Duc V. Le, Thanh Tam Nguyen-Huu

This paper examines how a developing country can benefit from trade liberalization. We develop a two-period model, comprising an autarky phase and a globalization phase, and a two-…

Hartman-Stampacchia theorem, Gale-Nikaido-Debreu lemma, and Brouwer and Kakutani fixed-point theorems

Pascal Gourdel, Cuong Le Van, Ngoc-Sang Pham +1

This paper uses the Hartman-Stampacchia theorems as the primary tool to prove the Gale-Nikaid{ô}-Debreu lemmas. It also establishes a cycle of equivalences among the Hartman-Stampa…

A note on first-order and transversality conditions in infinite-horizon continuous-time optimal control models

Stefano Bosi, David Desmarchelier, Ngoc-Sang Pham

We provide simple and easily verifiable necessary and sufficient conditions for infinite-horizon continuous-time optimal control problems. Under standard concavity and integrabilit…

New Formulations and Discretization Insights for the Electric Autonomous Dial-a-Ride Problem

Boshuai Zhao, Adam Abdin, Jakob Puchinger

The Electric Autonomous Dial-a-Ride Problem (E-ADARP) involves routing and scheduling electric autonomous vehicles under battery capacity and partial recharging constraints, aiming…

The Bi-objective Electric Autonomous Dial-a-Ride Problem

Yue Su, Sophie N. Parragh, Nicolas Dupin +1

The electric autonomous dial-a-ride problem (E-ADARP) introduces electric, autonomously driving vehicles and their unique requirements into the classic dial-a-ride problem, where p…

Wariness and Poverty Traps

Hai Ha Pham, Ngoc-Sang Pham

We investigate the effects of wariness (defined as individuals' concern for their minimum utility over time) on poverty traps and equilibrium multiplicity in an overlapping generat…

To Bubble or Not to Bubble: Asset Price Dynamics and Optimality in OLG Economies

Stefano Bosi, Cuong Le Van, Ngoc-Sang Pham

We study an overlapping generations (OLG) exchange economy with an asset that yields dividends. First, we derive general conditions, based on exogenous parameters, that give rise t…

Comment on 'Asset Bubbles and Overlapping Generations'

Ngoc-Sang Pham, Alexis Akira Toda

Tirole (1985) studied an overlapping generations model with capital accumulation and showed that the emergence of asset bubbles solves the capital over-accumulation problem. His Pr…

Equilibrium with non-convex preferences: some insights

Cuong Le Van, Ngoc-Sang Pham

We study the existence of equilibrium when agents' preferences may not beconvex. For some specific utility functions, we provide a necessary and sufficientcondition under which the…

(Non-Monotonic) Effects of Productivity and Credit Constraints on Equilibrium Aggregate Production in General Equilibrium Models with Heterogeneous Producers

Ngoc-Sang Pham

We show that, in a market economy, the aggregate production level depends not only on the aggregate variables but also on the distribution of individual characteristics (e.g., prod…

FDI versus R\&D in an endogenous growth model

Thanh Tam Nguyen-Huu, Ngoc-Sang Pham

We investigate the role of foreign direct investment (FDI) and research and development (R\&D) in the transitional dynamics of host countries using an optimal growth model. FDI may…

The relationship between general equilibrium models with infinite-lived agents and overlapping generations models, and some applications

Ngoc-Sang Pham

We prove that a two-cycle equilibrium in a general equilibrium model with infinitely-lived agents (GEILA) constitutes an equilibrium in an overlapping generations (OLG) model. Conv…

A Deterministic Annealing Local Search for the Electric Autonomous Dial-A-Ride Problem

Yue Su, Jakob Puchinger, Nicolas Dupin

This paper investigates the Electric Autonomous Dial-A-Ride Problem (E-ADARP), which consists in designing a set of minimum-cost routes that accommodates all customer requests for…
