In a closed economy a labor abundant country such as Indonesia would have low wages relative to capital rents and be a low opportunity cost producer of labor-intensive goods. A framework such as the HOS model predicts that as Indonesia opens to trade the REAL wages of laborers in that country should increase. Briefly, but as clearly as possible, explain in words the causal mechanisms that explain this result. Say the A sector is labor-intensive. Then the question is, when Pa/Pb rises, what happens next to explain the prediction. You can use bullet points (- or *), arrows ('-->' ) and brief phrases to keep your answer short but clear.

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
