In this assignment, students think about four events that would affect a country's exchange rate. Without actually drawing a supply and demand diagram, students say what direction, if at all, each curve would shiftâand whether the currency would appreciate or depreciate as a result.

The concept of price elasticity of demand was introduced in class. Elastic and inelastic goods were discussed. The impact that a change in price will have on total revenue was also presented.

During the lecture, labor demand and labor supply were discussed and were used to determine the equilibrium wage rate. Then, the concept of a minimum wage rate was introduced and the impact of the wage rate on the labor market was demonstrated graphically.

During the lecture, the competitive market was introduced. A graph was used to demonstrate a competitive market in which there was an economic profit. The profit motive causes an increase in supply. As additional producers enter the market, the price of the product or service decreases. In the end, price will decrease until the long-run equilibrium situation is reached which means that the economic profit decreases to zero.

In 1931, a severe drought hit the Southern and Midwestern plains. As crops died and winds picked up, dust storms began. As the "Dust Bowl" photograph shows, crops literally blew away in "black blizzards" as years of poor farming practices and over-cultivation combined with the lack of rain. By 1934, 75% of the United States was severely affected by this terrible drought.The one-two punch of economic depression and bad weather put many farmers out of business. In the early 1930s, thousands of Dust Bowl refugees ? mainly from Oklahoma, Texas, Colorado, Kansas, and New Mexico ? packed up their families and migrated west, hoping to find work. Entire families migrated together (such as the men shown in "Three generations of Texans now Drought Refugees") in search of a better life. Images such as "Midcontinent ? Family Standing on the Road with Car," "Drought Refugees," and "Untitled, ca. 1935 (Worn-Down Family in Front of Tent)" offer a glimpse into their experience on the road, and show that cars provided many families both transportation and shelter on the road. About 200,000 of the migrants headed for California. The state needed to figure out how to absorb the thousands of destitute people crossing its borders daily. One of their tactics was to document the plight of the refugees. In 1935, photographer Dorothea Lange joined the Rural Rehabilitation Division of the California State Emergency Relief Administration (SERA), a section of the Federal Emergency Relief Administration. She was assigned the job of using her camera to document the growing number of homeless Dust Bowl refugees migrating to California. She worked with Paul S. Taylor, a professor at the University of California, Berkeley, who was researching conditions of rural poverty in order to make recommendations on how to improve the workers' conditions. The work by Taylor and Lange played an important role in helping to raise public awareness of the crisis. The reports they made for the government included both data and striking images that revealed the desperate conditions in which the migrants lived and confirmed the need for government intervention. Stark images such as "Home of Oklahoma Drought Refugees" resonated with the public, and portraits of drought refugees like "Ruby from Arkansas" and others shown in this topic humanized the migrants for more fortunate citizens. In March 1936, Lange took what became one of her most famous images, "Migrant Mother." This image of a 32-year-old woman became an icon for the suffering of ordinary people during Great Depression.

The Dynamic Integrated Climate Change (DICE) model assumes a single world producer must chose levels for three simultaneously determined variables: current consumption, investment, and greenhouse gases reduction. The model is freely available in both a GAMS and Excel version. DICE allows both science and economics instructors to integrate a sophisticated economic model of climate change into their courses. The simulation is for upper-division courses where students have some background in microeconomics. The principle developer is William Nordhaus at Yale University.

This video segment adapted from NASA's Goddard Space Flight Center discusses how a drought can have negative effects locally, for example by increasing the number of forest fires, and also globally, for example by impacting air quality thousands of miles away.
