Open research questions in Economic Growth and Productivity

What the literature leaves open

• 4 Suggestions for Future Research Future research should investigate micro-level factors such as household production practices, access to credit, market integration, and gender dynamics in agriculture to provide a more nuanced understanding of the sector’s challenges and opportunities. These findings highlight that simply expanding land, labor, or capital inputs is insufficient to drive sustainable economic growth without corresponding improvements in productivity and efficiency.

• Translating these global structural insights into actionable, evidence-based economic policies for emerging regions—specifically ASEAN and the Philippines—yields the following core recommendations: 1. Transition to Productive Sovereign Leverage: Fiscal and planning authorities, such as the Department of Finance (DOF) and the Department of Economy, Planning and Development (DEPDev), may abandon defensive, purely austerity-driven budgetary frameworks. The government may utilize public borrowing as an active funding channel rather than a dead-end strain. To match the growth dynamics observed in advanced nations, debt accumulation may be strictly and transparently bound to high-multiplier capital infrastructure investments, public utilities, and asset development, coordinated with agencies like the Department of Public Works and Highways (DPWH). This ensures that the long-term economic returns systematically outpace and cushion debt-servicing obligations. 3. 2. Establish Price and Labor Stability as Fiscal Pre-conditions: Central banks (such as the Bangko Sentral ng Pilipinas) and economic planning agencies may prioritize absolute price and labor market stability not merely as isolated targets, but as core requirements for fiscal policy success. Since inflation and unemployment structurally degrade the state's internal capacity to spend efficiently, authorities, potentially in collaboration with the Department of Agriculture (DA) and the Department of Trade and Industry (DTI), may implement preemptive supply-side interventions—including localized food reserves, agricultural logistics stabilization, and targeted corporate incentives—to shield public budgets from sudden domestic macro-shocks. Institutionalize Workforce Activation Channels: To fully capitalize on the independent "Human Capital Track" and maximize demographic dividends, policymakers, led by institutions like the Department of Labor and Employment (DOLE), may eliminate institutional and socio-cultural barriers to workforce engagement. National strategies, supported by bodies such as the Philippine Commission on Women (PCW) and the DTI, may focus heavily on expanding female labor force participation (through accessible childcare and parental protections), formalizing informal employment sectors, and lowering regulatory entry costs for small and medium enterprises (SMEs). Because the returns of workforce activation flow directly into the real economy without straining public budgets, an expanded labor supply provides a resilient, non-inflationary buffer for sustainable and inclusive regional growth.

• Future research could address these limitations by employing longer time se- ries, incorporating additional countries, or conducting disaggregated analyses at the sectoral or regional level. Additionally, the study does not account for potential structural breaks, policy changes, or external shocks that could influence the relationships under investigation.

• While prior research (Hidalgo & Hausmann, 2009; Liu & Gao, 2020; Neagu, Neagu, & Gavurova, 2022) links complexity to growth, limited studies focus on its determinants in transition economies.

• The pattern of intensive use of ICT in services tends to be replicated in transition economies, however the evidence of ICT impacts on growth and productivity is lacking at the aggregate and industry level owing to deficient data and methodological problems.

• (2) The still open questions are: What speeds up capital accumulation and what conditions are necessary for technological improvements? What are the ultimate causes of economic growth? The present study hypothesizes that the missing ingredient in the theory of economic growth is incentives, which strongly depend on private property rights.

• The author first assesses the achievements of the state in terms of various national performance indicators, concluding that it has made strong progress in the development of a technology-based economy albeit in a relatively small number of technology sectors and with most of the beneficial impacts limited to the state's major city Atlanta.

• Problems include the lack of major metropolitan areas, limited research capabilities of the local universities, limited industrial research and development, a lack of research infrastructure, an over dependency on a resource-based economy, and the problem of competing with well-established technology regions.

• The moral I draw from all this, somewhat reluctantly I must admit, is that we just do not know at present whether existing levels of public financial support for science:are justified or not. The contribution of science to the economic base of civilisation may be massive, or it may not be. In a broad sense, the difference between contemporary standards of living and those of primitive man must be due to some contribution of superior knowledge, and restraint i n population growth. But:how far the organised pursuit of knowledge, in the form o f science a s it exists today, can be credited:with responsibility for the economic basis of contemporary civilisation, and how far society gains from public support of science, remain open questions.

In some respects, however, the situation is much more Keynesian than we would imagine, and the complementary factors which are lacking to make Keynesian solutions relevant may be more in the field of planning policies and aid practices or in the field of entrepreneurship and administration than in inescapable shortages of physical capital.

• It is an open question whether GNP or the nonmonetary index more correctly measures the level of economic development in Japan. Since preferences vary widely among national groups, there is probably no alternative to an arbitrary decision based on the judgment of the investigator.

• This faulty concept of the system of economic contracts was of course quite in keeping with the strict centralization of planning and management and a notion of the plan that was not understood to be a plan of total development, but only of a portion of eco nomic obligations confined almost exclusively to the specification of balance sheets, regard less of whether or not the specifications were compatible with the other parts of the plan.

• Some of them are of course multi- product industries whose performance needs to be investigated under several headings, but the problems arising in this connection are different in kind and will be considered separately. *4 My own reading of the situation, however, is that the overstatement on those counts is insufficient to redress the balance, and that the 'true' rate of growth which would have resulted from the strict application of the principles of selection and weighting underlying the American index86 (if that were possible) may be found somewhere between Professor Hodgman's estimate and the official index, though probably much nearer the former.

• We hope above all that studies of this kind will be able to show the richness of new methods and the fulness of that harvest which remains to be gathered, and to arouse the interest of young people, inspire them to take up careers, so that our twentieth century will evoke in the memory of man less the birth of atomic energy than the adolescence of the sciences of man. Employment for tertiary goods, not being limited by the demand of consumers, which remains unremittingly active, is limited only by employment in the first two sectors.
