Projects

The International Food Policy Research Institute (IFPRI) and the Papua New Guinea National Agriculture Research Institute (NARI) have teamed up to support data-driven policy dialogue and formulation. This project is designed to provide an in-depth agricultural strategy report to provide the foundation for informing key agricultural development challenges and opportunities in Papua New Guinea (PNG). Analysis for the report will draw from recent data collection efforts in PNG and utilize comparative analyses from other countries in the region to better evaluate the key factors of production to improve competitiveness within the country and inform investments and programs aimed to jumpstart the agricultural transformation process throughout all stages.

Regional implications of public investments and external shocks in Papua New Guinea: An economywide analysis

Improvements in telecommunications have enabled a tremendous increase in the flow of information across Papua New Guinea. Although transport costs remain high between various parts of the main island of Papua New Guinea, as well as between the main island and other parts of the country (e.g. the islands of New Britain and Bougainville to the East), phone and internet conditions enable government, traders and entrepreneurs to share market information that reduces transactions costs and improves market function. Nonetheless, there remain major differences in agricultural production, income sources and demand patterns across regions that are important to take into account in analyzing the impacts of external shocks and formulating development strategies. Earlier work on PNG by Schmidt et al., (2021) explored the effects of Covid-related income and world rice price shocks with a partial equilibrium model of PNG’s rice economy. Diao et al., (2021) used a regional multi-market model to analyze broader effects of Covid-19 and other shocks to agriculture and household incomes in four regions of PNG. Various other studies, including Dorosh and Pradesha (2022) and Diao et al. (2024), used national computable general equilibrium (CGE) models of PNG to analyze exchange rate, terms of trade, and productivity shocks on various household groups. In this paper, we extend these earlier analyses through use of a new regional CGE model that utilizes recent household survey data, including the 2023 IFPRI PNG rural household survey. The plan of this paper is as follows. The next section provides an overview of agriculture and economic growth in PNG over the last decade, highlighting the almost constant share of agriculture in GDP and very low per capita agricultural GDP growth rate. Section 3 describes the regional disaggregation of the PNG economy and the structure of household incomes and expenditure as reflected in the economywide database, the Social Accounting Matrix (SAM), used in this analysis. Section 4 then presents a summary of the regional economywide model. (Details of the model are found in the annexes and in the references included in the paper.) Design of the model simulations and simulation results covering investments in agriculture and transport sectors, as well as world price shocks are discussed in Section 5. Chapter 6 concludes with a summary of the main findings and policy implications, as well as suggested areas for further work.

Brief

Implications of exchange rate overvaluation and world price shocks for PNG

2025Dorosh, Paul A.; Pradesha, Angga

Implications of exchange rate overvaluation and world price shocks for PNG

The large inflow of foreign capital to fund PNG investments in natural gas pipeline and processing infrastructure resulted in a surge in inflation beginning in 2011. Costs of production of tradable goods such as coffee and palm oil rose more (in kina terms) than their output prices, reducing the profitability of these sectors. These price distortions have continued to the present day, as restrictions on access to foreign exchange (mainly through delays in the release of funds) as demand for foreign exchange exceeds supply made available to the public. This policy note reviews PNG’s exchange rate policies and uses an economy-wide simulation model1 to quantify the impacts of these distortions. We conclude with a discussion of policy implications, highlighting the effects of a possible devaluation / depreciation of the kina.

Commercialization of Papua New Guinea’s vegetable sector: Identifying constraints using quantitative, qualitative, and large language model methods

This paper evaluates the constraints within Papua New Guinea’s vegetable sector, drawing on large scale household surveys, extensive qualitative interviews with key stakeholders, and Large Language Model (LLM) methods. Our survey data reveal that vegetable production is ubiquitous, with almost all households surveyed (91%) growing at least one vegetable. Indigenous varieties, such as leafy greens (96%) and fresh beans (69%), are widely cultivated across regions, while high-value vegetables like onion (17%) and tomato (19%) show more regional concentration. Over half (53%) of PNG vegetable farmers sell their produce, with farmers located in the nonseasonal highlands agro-ecological area leading in market participation (66%), contributing to an overall commercialization rate of 24% (defined as the share of pro duction sold). However, modern input use, particularly improved seed adoption, significantly lags behind output commercialization in all agroecological zones except the islands survey areas. The quantitative analysis, using the PNG Rural Household Survey 2023, and the qualitative analysis, drawing from both manual review and LLM-assisted processing of in-depth interview notes, consistently identify poor feeder roads as critical bottlenecks for every stakeholder across PNG’s vegetable value chain. Beyond transportation, these interviews repeatedly highlighted persistent seed supply shortages and high seed costs as significant hurdles. Since PNG depends on imported vegetable seeds, several structural and procedural barriers contribute to these shortages. These include potentially arduous quarantine procedures, limited foreign exchange for seed imports, and cumbersome permit processes, often leaving major distributors with insufficient stock. These reported bottlenecks may contribute to the low improved seed adoption and use reflected in the household survey analysis.
