Abstract:

Evidence from Mercosur suggests that eliminating duty drawbacks for intra-regional exports would lead to increased counterlobbying against protection of intermediate products. Without the duty drawback, the common external tariff would have been an estimated 3.5 percentage points (25 percent) higher on average.

Duty drawback (or rebate) systems reduce or eliminate the duties paid on imported intermediate goods or raw materials used in the production of exports. When a firm imports an intermediate product for use in the production of an export good, tariff payments on the imported intermediate good are either waived (duty drawback) or returned to the producer once the final product is exported (rebate). These incentive systems are often justified on the grounds that they tend to correct the anti-trade bias imposed by high tariff levels.

The problem with this line of reasoning is that it assumes that tariffs are predetermined policy variables; if they were, the easiest way to reduce their anti-trade bias would be to eliminate them. But this is rarely done because existing levels of protection correspond to a political economy equilibrium difficult to modify in the presence of lobbying pressures.

Cadot, de Melo, and Olarreaga show that in a political economy setting where tariffs and duty drawbacks are endogenously chosen through industry lobbying, full duty drawbacks are granted to exporters that use imported intermediate goods in their production. This in turn decreases their incentives to counterlobby against high tariffs on their inputs. Indeed, under a full duty drawback regime, tariffs on intermediate goods are irrelevant to exporters because they are fully rebated. In equilibrium, higher tariffs will be observed on these goods.

Creating a regional trading bloc alters the incentives by eliminating duty drawbacks on intraregional exports, which leads to lower tariffs for goods that intraregional exporters use as inputs.

Evidence from Mercosur suggests that eliminating duty drawbacks for intra-regional exports would lead to increased counterlobbying against protection of intermediate products. Cadot, de Melo, and Olarreaga estimate that without this mechanism, the common external tariff would have been 3.5 percentage points (25 percent) higher on average.

Facts on IBM Software

There are other applications that do not work well in such an environment, for example, an electronic trading system in a bank. Such applications typically use tricks that can greatly improve performance such as partitioning, multi-threading and write through caching. These are applications that can exploit asymmetric clustering. An asymmetric cluster is practically the opposite of a symmetric cluster: Applications can declare named partitions at any point while it is running partitions are highly available, are mobile within the cluster and usually only run on a single cluster member at a time. Incoming work for a partition is routed to the cluster member hosting the partition. The application is amodal. Partitions have a lifecycle of their own and can start background threads/alarms as well as respond to incoming events whether they are IIOP/HTTP or JMS/foreign messages.

The integration of Lotus into IBM continues. Today, it is a software brand within IBM's Software Group. Within Lotus, there is still a strong sense of unity. Many employees formerly within Lotus, though they have moved into and embraced the rest of IBM, still identify with Lotus and see themselves as part of the Lotus community.

Rational provides open, industry standard tools, best practices and services for developing business applications and building software products and systems, including embedded software for devices such as cell phones and medical systems.
