There are many causes due to Haiti's decline in the economy. Haiti's underdevelopment is due mostly due to the cause of overpopulation. No serious internal market developed in Haiti since the beginning when the French had control over the market. David Nicholl's, Haiti in the World Economy said, "Haiti is a highly dependent and underdeveloped economy which independent Haiti inherited in 1804." So how is Haiti's economy faring compared to other Caribbean countries? Well, Haiti's economy continues to decline today. The Haitian economy and businesses do not have a solid foundation. Open-air markets play a big role in the Haitian economy. Through the open-air market and with the help of an agent, the Haitian market is able to perform many transactions. Nearly 70% of all Haitians depend on the agriculture sector, which consists mainly of small-scale farming. This population employs about two thirds of the work force that makes up the economy or the work force in Haiti. Another reason why the Haitian market is continuing to fail is because there was no combined integrated market, which controlled and oversees the transactions. When materials are produced in the market, that material is not shipped back to the local market but to the many small broken down markets. So the country on a whole is relying on these small markets instead of the "big gun" market that is basically doing the checks and balances of the country. Instead of an export-centered economy, the country was and is still continuing to focus on an import-centered economy which forces the Haitians to continue to live in poverty. Haiti's final blow of underdevelopment occurred when the Duvalier's came into power in Haiti. The Haitian Economy had no chance. The American Occupation Act helped with the 29-year dictatorship of the Duvalier presidency and they took control of the country and destroying Haiti's economy. In addition to Duvaliers presidency, outside ownership of businesses in Haiti have impacted the industry. The reason that plays a major role is the business owners usually do not have the income to capitalize on their company. Because they do not have any and most likely they do not have access to funds, they have to look to outside foreign investors. "Most Haitian businessmen do not have the capital to buy the larger privatized entities, the major industries are likely to be transferred to US, Canadian, or French control." So the Haitian economy never gets a chance because they do not have the available funds to perform these transactions with the "top gun" companies.
