Fanning (2005), Ch 6 Economic Base Analysis Interpreting Local Employment Numbers
What is the Economic Base? • Economic Base: Activities that bring income into a city – Export activities: Products or services provided to the outside world (most manufacturing; higher education and research, advanced health care) – Activities that attract money (retirement, tourism) • Secondary (Local) Activities: Activities that recirculate income in a city (local government, local merchants and services)
Economic Base Multiplier • The idea: As goes the base, so goes the city. One extra job in the basic sector may cause 3 extra non-basic jobs. • Multiplier effect: Base income is respent, producing additional income
The Economic Base brings money In 5. Total community income is the sum of export dollars plus respent dollars 1. “Exports” bring dollars into the community 2. Most is respent $$$$$$ on local goods and services Savings $ $ 4. Some “leaks” into savings $$ $ $$$$ $ 3. Some “leaks”through outside expenditures
The Economic Base Multiplier • The multiplier is total employment divided by basic employment. • I. e. , divide total employment into basic and nonbasic: T = B + NB • The multiplier: k= T/B. E. g. , k=3. 0 • Estimate future growth in basic employment = c. B. E. g. , 5, 000 new workers • Then est. growth in total emp = kxc. B • E. g. , est. c. T = 15, 000 = 3. 0 x 5, 000.
Examples of Basic Employment • Mining and extractive industries – oil in Houston • Manufacturing – cars in Detroit • Federal government – military bases in Norfolk. • State and local government – state university or hospital • Retail & financial services that attract customers – major mall in a rural area.
Nonbasic (“Service”) Employment • Local professionals – attorneys, doctors, real estate brokers, appraisers, lenders • Most retailing – gas stations, grocery stores, etc. • Local construction workers • Local government workers – school teachers, city hospital employees, etc.
Obtain employment data • Quick Indicators – USA Counties in Profile http: //www. stats. indiana. edu/uspr/a/us_profile_frame. ht ml • See next slide for how to use Census data for EB analysis: – U. S. Census Detailed Tables http: //www. census. gov
Location Quotient an Indicator of Economic Base • Compute the percentage of total employment in a given industry • Example: Suppose education is 20% • Compute the same percentage for the national economy • Suppose education in the national economy is 9% • Compute the ratio of local to national percentage: • Location quotient = 20% ÷ 9% = 2. 22 • Interpretation: Local economy has 2. 22 times the normal education employment; excess is export employment
Limitations of Location Quotients (LQ’s) • They assume that: – Consumption patterns are constant from one local (e. g. , metropolitan) area to another. – Labor productivity is the same in all metro areas. – Each industry produces a single homogeneous good. • The net result of these assumptions is that location quotients usually underestimate basic employment. • However, the LQ method is simple and data are readily available.
Supply Factors Affecting a Community Economic Base • Labor force characteristics – – – Special skills and experience Education level Unionization Work ethic Other? • Quality of life • Leadership – Financial support – Government support (subsidies, land use regulation)
