Hypotheses from the recent economic literature on heterogeneous firms and international trade are evaluated for food beverage industry. Using new survey evidence firms, an econometric model was developed to link a firm's probability of exporting back characteristics such as ownership structure, size, product type. Trade policy, COVID-19 pandemic, search costs finding overseas markets were cited...

There is little disagreement among most economists that countries benefit from trade liberalization. Yet, whether unilateral, multilateral (through the World Trade Organization) or through regional integration agreements (RIAs), trade liberalization has been one of the most controversial economic issues of our time. It is the focus of everyone from politicians to union leaders and anti-globaliz...

This paper is motivated by three observations about the link between international trade and international business cycle synchronization: (1) a large increase in trade in manufactures over the last 30 years, (2) a larger fraction of trade between core and periphery regions relative to core regions is in the form of production sharing, (3) crosscountry output correlations have increased between...

Predicting the future evolution of complex systems is one of the main challenges in complexity science. Based on a current snapshot of a network, link prediction algorithms aim to predict its future evolution. We apply here link prediction algorithms to data on the international trade between countries. This data can be represented as a complex network where links connect countries with the pro...

This paper presents the trade-offs that exist between the blocking probability, the size of the switching elements, the offered load and the link capacities in an ATM-based Banyan multistage interconnection network for QoS-sensitive applications. We present a quasi-analytical study which indicates that, as the link capacity between switching elements is increased, the blocking probability reduc...

The torque sensor is used to measure the joint torque of a robot manipulator. Previous research showed that the sensitivity and the stiffness of torque sensors have trade-off characteristics. Stiffness has to be sacrificed to increase the sensitivity of the sensor. In this research, a new torque sensor with high sensitivity (TSHS) is proposed in order to resolve this problem. The key idea of th...

Regulating the transmission rate of non real-time applications offers enhanced flexibility for QoS management and capacity control on a CDMA link. For a system working at saturation conditions, i.e., with the highest number of on-going transmissions, controlling data rates can further enhance its capacity. A more thorough investigation of this possibility and the trade-offs involved is presente...
