i need only one of the options from above

One problem associated with free trade is the loss of local jobs to international competition.

The problem associated with free trade from the given options is the "loss of local jobs to international competition." This issue occurs when domestic industries are unable to compete with foreign producers who can offer lower-cost goods or services. As a result, some local businesses may be forced to downsize or shut down, leading to a decrease in job opportunities for the local workforce.

To understand this problem, one can analyze the impact of free trade on industries and employment. This involves considering factors such as:

1. Comparative advantage: Free trade allows countries to specialize in the production of goods or services in which they have a comparative advantage, meaning they can produce more efficiently and at lower costs compared to other countries. This can lead to increased international competition for domestic industries that are outperformed by foreign competitors.

2. Import penetration: When foreign goods or services flood the domestic market due to free trade agreements, it can create challenges for local businesses. Domestic industries may struggle to compete with lower-priced imports, and this can result in job losses as companies become less viable or shift their operations to countries with lower production costs.

3. Displacement and adjustment: In industries heavily impacted by international competition, workers may lose their jobs or experience reduced wages and hours. The process of workers transitioning to other sectors or retraining can be challenging and time-consuming, leading to economic dislocation and potential social tensions.

By understanding the underlying principles and consequences of free trade, one can identify the problem of job loss to international competition and its impact on local economies and workers.
