Introduction External influence on national urban systems dates back to colonial times.Cities were the strategic contact points between colonizer and colony.Evolution of ports and transport systems was strongly shaped by trade and investment decisions of colonial authorities.Indeed, the geographic location of ports was critical to choice of primary and secondary urban centers.

Focus on effects of economic openness on:
balanced/unbalanced regional developmentregional income growthpoverty reduction or welfare of the
poor.
Introduction (cont’d)Two views on economic openness and regional development:
economic openness & urban concentration inversely related as trade spurs growth of countryside, given that exports are not linked to the domestic market (Krugmanand Livas 1996 – new economic geography models). trade and FDI reinforce urban primacy as economic activity is concentrated in capital metropolis and inter-city infrastructure is inadequate (e.g., Fuchs and Pernia 1987 on Asia; Rivas 2007 on Mexico).
Data and ApproachData on Philippines’ 14 regions in 1988-2000 and 17 regions in 2009-2013.Significant liberalization measures introduced, effecting beginning in 1994… GDP growth of over 5% in 1994-1997 and to >6% in 2010 onward …
GRDP data are from National Income Accounts, socioeconomic and fiscal data from relevant government agencies, household data on poverty from Family Income and Expenditure Surveys, etc.
Discern general patterns across regions and over time.
Econometric analysis.
Patterns of Regional DevelopmentEconomic Indicators
Regional imbalance appears to be persisting• Metro Manila (MM or NCR), as expected,
continues to have the highest income per capita @ Php196K in 2013
• widening interregional income differential– MM’s GRDP per capita close to 2.8 times
national average, about 2.3 times that of next highest (CALABARZON), and more than 13 times the poorest region (ARMM)
• MM’s share in GDP rising from 30% in 1988 to 36.3% in 2013.

Regional Patterns…Most of the special economic zones (SEZs) are located in 4 regions: NCR, CALABARZON, Central Luzon, and Central Visayas.The 4 regions hosting the SEZs are the main recipients of both foreign and local investments.Pattern of exports reveal essentially the same relative dominance of the 4 regions, though exports appear more spatially dispersed.NCR’s primacy in exports and investments appears to be waning.
Regional Patterns…Social Indicators
Social development reflects not only region’s economic performance but also efficacy of public spending for social services at the local level• inter-regional disparities not as sharp as
economic indicators• Mindanao regions continue to fare poorly
relative to other regions in terms of education and health indicators.
Regional Patterns…Poverty Indicators
• Poverty incidence at national level on a slow downtrend, 27.3% (2000) to 25.2% (2012).
• At the regional level, poverty incidence is lowest in MM (3.9%) and highest (and rising) in ARMM (55.8) and Eastern Visayas (45.2) in 2012.
• Similar pattern shown by consumption expenditure per capita (welfare) of poorest quintile – even falling for some Mindanao regions and Eastern Visayas in 2012 from 2006.
• Elasticity estimate from cross-regional OLS regression is 0.42, suggesting a 10% increase in regional incomes raises well-being of the poor by just 4.2%, implying inequality-increasing effect of regional income growth.

Regional Patterns…Summary thus far
MM remains pre-eminent in the country’s economic and social landscape.Regional disparities are revealed more sharply by economic indicators than by social indicators• narrow differentials in social indicators suggest
only slight variations in efficacy of social policy at local levels, regardless of regional economic differentials.
• regional poverty rates vary widely and are more closely associated with economic than with social indicators.

Estimating equations PCEPOORrt = PCEPOORrt (GRDPrt, LOCALrt, ICONDr) (1)GRDPrt = GRDPrt (LOCALrt, LOCALrt-1, OPENrt) (2) OPENrt = OPEN rt (LOCALrt, LOCALrt-1, OPENrt-1, GRDPrt)(3)
where:PCEPOORrt = per capita expenditure of the poor in region r at time t
GRDPrt = income of region r at time tOPENrt = economic openness (exports-GRDP ratio) in region r at time t
LOCALrt = local factors in region r at time tICONDr = initial conditions of region r
Explanatory notesEquation 1 shows how the welfare of the poor is influenced by the region’s income, local factors, and initial conditions. Equations 2 and 3 take into account the endogeneity of GRDP and economic openness as both are affected by each other and by local factors.
Equations 1-3 are estimated using the three-stage least squares (3SLS) method. The 3SLS estimation procedure takes into account not only the endogeneity of the three variables (per capita expenditure of the poor, regional income, and exports) but also the interaction between equations through the covariance matrix of the equations’ disturbances.
For the estimation, we use panel data on the 14 regions for the years 1988, 1991, 1994, 1997, and 2000 (i.e., four 3-year intervals), as well as 2009-2013 on 17 regions . Our empirical model is constrained by the available data. To test for dynamic effects, current as well as lagged values are used.
Empirical results

Determinants…Regional income growth is influenced by
trade opennessprevious period’s spending for social serviceshuman capital stockprimacy dummy implies that NCR maintains income-dominance over all regions.Incidentally, the Economist (January 24-30, 2015, pp. 63-65) reports research (Bjorn Lomborg, Copenhagen Consensus Center) showing that trade liberalization, in general, by far results in the biggest benefit (bang per buck) ($2,011/$1) spent among various development policy measures; next is access to contraception ($120/$1) –better than spending on, e.g., environment as most developing countries actually negligible polluters globally.
Determinants…Well-being of the poor is positively influenced by
economic growthpublic spending for social services, including agrarian reforminfrastructure (electricity, roads) human capital stock.
No clear evidence on direct link from trade openness to poor’s welfare/incomes, except thru economic growth (Krueger & Berg 2002; Winters et al. 2004).
Conclusion and Policy ImplicationsEconomic openness is beneficial to regional economic growth and – through growth – poor’s welfare/poverty reduction.But, due to unbalanced regional development, to begin with, effect of openness limited to relatively developed regions, incl. corollary effect on poverty.Thus, growth of such areas as CALABARZON, Central Luzon, CAR, and Central Visayas appreciably attributable to external factors (trade & investment, not to mention overseas Filipino remittances).External factors by themselves cannot be relied upon to bring about more balanced regional development or narrower spatial disparities.
Conclusion…To foster more balanced development, public policy must take a more deliberate lead and vigorously encourage the private sector to play a more active role.Good physical and social infrastructures are crucial, as are strong national and local governance, and a conducive investment climate.Only then, perhaps, can openness exert a wider spread effect on regional growth and poverty reduction.
