Book chapter

  • The Indonesian transboundary haze game: Countering free-riding and local capture
    Rusli, Ridwan D., 2018, Publisher: Chapter 13 in Pollution Across Borders: Transboundary Fire, Smoke and Haze in Southeast Asia, Editor Prof. Euston Quah, Nanyang Technological University, Singapore,
    We identify solution strategies and policies to abate man-made forest fires in Indonesia, mitigate the resulting transboundary haze pollution and enforce zero-burning regulation. Bargaining for abatement and enforcement exhibits characteristics of a repeated game-of-chicken with cross-border free-riding and local capture problems. The combined free-riding and capture problems must be tackled by shifting the incentives of the Indonesian central government, local bureaucrats and business elites, plantation and forestry companies, farmers and residents. Neighbouring country governments can offer technical and financial incentives to the Indonesian central and local governments, residents and farmers, while asserting control over regional plantation companies with business and financial interests in their jurisdictions.
  • The logic of energy policy: The case of upstream oil, gas, coal and downstream oil sectors in Southeast Asia
    Rusli, Ridwan D., April 2013, Publisher: Co-editors Hong, Mark and Amy Lugg, Asan Institute of Policy Studies (AIPS) and Institute of Southeast Asian Studies (ISEAS), Singapore,
    This chapter describes a systematic approach to energy policy in Southeast Asia. It analyzes the interdependence between two out of the three main objectives of energy policy, namely economic competitiveness and energy security. The focus is on the Southeast Asian upstream oil, gas and coal as well as downstream oil refining and distribution industries. The framework takes on a holistic approach to the making of energy policy. It can be extended to other alternative energy sources and fuel types, to the downstream gas and coal processing, transport and distribution infrastructure sectors. This framework can also be applied to more specifically target the interdependence between economic competitiveness, energy security and environmental sustainability. The analysis starts with an examination of country-specific geographic, demographic, economic and socio-political determinants of energy policy. These provide the basis for selecting an optimal set of industrial, sector, trade, investment and fiscal policy instruments, as well as a feasible implementation program. The derived policy grid is compared to the actual energy policies of selected Southeast Asian countries. It is observed that all governments have relatively detailed energy sector policy blueprints, albeit with variations across sub-sectors especially in relation to the relatively recent alternative energy and climate change sub-sectors. However, the implementation of these energy policy programs in some countries is hampered by institutional and socio-political constraints, and the need for governments to pursue more rigorously commercial strategies.

Book review

  • Review of Vlado Vivoda: Energy security in Japan, challenges after Fukushima
    Rusli, Ridwan D., 2016, Publisher: Singapore Economic Review 61:4,
    The study of Japan's energy security challenges post-Fukushima is not only critical to this highly industrialized nation that possesses almost no indigenous resources, but also of great relevance to other countries exposed to imported energy feedstocks, whose energy mix include nuclear power generation, and whose industries are regulated and affected by political and institutional inertia. The author argues that Japanese energy policy is embedded in the country's specific political, economic and social context. While energy transitions are inherently difficult and costly, the implementation of new energy policies is further constrained by existing interests and institutions. This path dependency makes it more difficult for government and industry to engineer major shifts in energy mix and develop new energy technologies in a shorter time period.

Journal Article

  • State-Owned Firms and Private debt
    Picard, Pierre M., and Ridwan D. Rusli, October 2018, Publisher: Journal of Public Economic Theory 20:5, pp. 672-702,
    We study the role of private debt financing in reducing government transfers and information costs in a state-owned firm. We show that debt contracts allow the government to reduce socially costly subsidies by letting undeperforming state-owned firms default. When the firm has private information, the government uses debt to reduce the firms` information rents. The option of default and privatize allows the government to stop subsidizing the firm. We identify the conditions under which information costs outweigh privatization costs and a positive debt level benefits governments.

  • Reinterpreting social processes: How system theory can help to understand organizations and the example of Indonesia’s decentralization
    Duek, Ana, Brodjonegoro, Bambang, and Ridwan D. Rusli, 2010, Publisher: Emergence: Complexity & Organization 12:4, pp. 30-56,
    The complexity of social systems is characterized by the possible occurrence of simultaneous or sequential processes of structural change. This paper is focused on certain types of structural change: (i) those produced by assembly and disassembly and (ii) those resulting from decisional and/ or behavioral processes, including both bottom-up and top-down processes. These general concepts from system theory are applied to the case of Indonesia’s decentralization. The well-known story of Indonesia’s remarkable transition to a democratic society and decentralized nation is presented here in an alternative manner that has allowed us to identify types of structural changes in empirical events. Ultimately, this analysis offers a better explanation of the intrinsic complexity of any social organization and demonstrates an approach to similar problems.

  • Financing and Regulation for Developing Country Natural Resource and Energy Industries
    Rusli, Ridwan D., mimeo 2013, Publisher: University of Luxembourg
    This thesis summarizes my PhD research on the institutional and political economy aspects of the resource, energy and infrastructure industries in developing countries. The papers that constitute this thesis relate to my previous work on natural resource and energy policy as well as my research in public finance and fiscal decentralization. In the first paper Pierre M. Picard and I use a contract-theoretical model to study the role of private debt financing in disciplining a state-owned firm. In the second paper we model and examine the impact of price caps on the welfare of build-operate-transfer concessions. In the third paper, written with James Cust, we use a panel regression to analyze direct and fiscal spillovers related to resource extraction across Indonesian districts.

  • Energy Transition and Energy Security in Germany: A Path to Sustainability and Security
    Chang, Youngho, Ridwan D. Rusli and Jackson Teh, Forthcoming 2021, Publisher: Technische Hochschule Köln
    We use the 4A framework of energy security to analyze Germany’s energy transition (“Energiewende”) over the last 20 years. While Germany’s forced build-up of renewables capacity and exit from nuclear and coal is a pioneering achievement among export-oriented, industrialized nations, the process has been and continues to be very costly. We find that, while the acceptance of climate change policies is very high among its society and voters, affordability to energy consumers and availability of energy resources have steadily decreased in recent years. As a result of high renewables feed-in tariffs and fuel taxes Germany’s households pay the highest electricity tariffs and among the highest fuel prices worldwide. Part of the country’s fiscal capacity is required to support energy-intensive industries. Exit from nuclear and coal electricity production necessitates increasing natural gas imports, which in turn creates geopolitical dependency on gas producing countries, requires extensive collaboration with European neighbors and partially undermines the benefits of the coal exit. Growth in renewables capacity has slowed down, hampered in part by local public resistance and increasing bureaucratic hurdles. Moreover, the technological leadership of the country’s engineering-oriented multinationals and SMEs (“Mittelstand”) has been challenged by increasingly sophisticated, highly efficient competitors, for example from China. To ensure German energy security in the long run, the country must accelerate significant domestic and European-wide renewables capacity, infrastructure and interconnector investments.
  • Transboundary Haze Games: Local Capture and Common Agency
    Rusli, Ridwan D. and Youngho Chang, September 2021, Publisher: Technische Hochschule Köln and University of Luxembourg
    We study how transboundary, intergovernmental fire and haze negotiations interact with local, subnational government collusion and capture in a decentralized country. The local government collusion and capture problem is modelled as a competing principals and common agency problem that interacts with the central government's transboundary game of chicken. The results show that the central government can persuade farmers and prevent burning when the incremental benefits from slashing and burning are lower, the total direct and indirect costs and damages of fire and haze are higher and the required enforcement and abatement costs are not too high. Neighbouring governments can help mitigate the central government's budget constraint and punish violating multinational companies. We develop a multitask multiprincipal framework to expand our solution set to include partial burning outcomes and negative compensations. The results inform on a set of policy strategies to these complex transboundary fire and haze negotiation and local capture problems.

  • Gojek: From Ride-Hailing App to Diversified and Sustainable Platform Business Model
    Rusli, Ridwan D., Forthcoming 2021, Publisher: Institute of Global Business and Society (GloBuS), Technische Hochschule Köln
    We show how prisoner's dilemma-type competition problems can be mitigated through rapid platform diversification and ecosystem expansion. We analyze a ride-hailing company in Southeast Asia, Gojek, whose network grew to more than 170 million Users comprising consumers, partner-drivers, merchants and complementors within a few years and already achieves higher contribution margins than ride-hailing peers Uber and Lyft. Its ecosystem integrates ride-hailing, food delivery and logistics, merchant solutions, e-commerce, marketplace and advertising, payments and fintech offerings. The company continues growing its network of complementors and App developers, expanding content and gaining critical mass in consumer data analytics and advertising. We compare the company's growth and diversification trajectory with those of its main international rivals and peers. The company's rapid growth and future potential is analyzed using Cusumano's (2012) Staying Power and Six Principles, Hax and Wilde's (2003) and Hax’s (2010) The Delta Model as well as Santos' (2016) home-market advantages frameworks. The recently announced multi-billion-dollar merger with one of Southeast Asia's largest e-commerce majors lends additional support to the above arguments.
  • Subnational Government Budgets and Resource Revenues in Indonesia: Indications of Resource Blessings?
    Rusli, Ridwan D., and Wessel N. Vermeulen, Research Paper 222, 2019, Publisher: Oxford Centre for Research in Resource Rich Economies (OxCarre)
    We examine the economic consequences of resource extraction and the associated revenue windfalls on subnational government revenues and spending patterns. Making use of Indonesia’s fiscal sharing rules and an offshore oil and gas production instrument, we find a positive impact of resource revenues on the center-local balancing funds including the general allocation fund, despite the latters’ fiscal re-balancing purpose. Fiscal windfalls from resource extraction increase public sector spending on capital and infrastructure projects as well as public goods and services, with positive spillover benefits on local tax revenues. At the same time spending on personnel and administration increases less and decrease as percentage of total expenditures. Interaction with district economic governance index data indicates enhanced infrastructure spending but also increases in the balancing funds.

  • The economic spillovers from resource extraction: a partial resource blessing on the subnational level?
    Cust, James, and Ridwan D. Rusli, 2014, Publisher: Economic Governance Centre, NTU, Discussion paper 2014-02,
    We examine the economic consequences of resource extraction and associated revenue windfalls, measured at the subnational level. Our analysis focuses on variations across Indonesian districts and municipalities to estimate the spillover effects on economic activity, measured in terms of local GDP. Two important channels are identified: direct spillover effects from extraction activity, and the fiscal spillovers from local government spending associated with revenue windfalls from extraction activity. We use Indonesia`s fiscal sharing rules to quantify and disentangle these two channels by application of an instrumental variable. We show that the main economic gains accrue via transfers to, and spending by, local government. While direct project-level investments and production contribute to measures of overall GDP, these are found to be largely driven by the value of oil extraction, with only limited evidence for a direct impact on non-oil GDP. In contrast to other works, it appears that regionally decentralized government spending can be growth-enhancing over the decade surveyed. We argue that resource endowments do contribute to increased economic activity at the subnational level in Indonesia, but may lower the overall growth effect of spending.

  • State-owned firms: Private debt, cost revelation and welfare
    Picard, Pierre M., and Ridwan D. Rusli, Nov 2012, Publisher: CREA Discussion Paper 2012-10,
    We study the role of private debt financing in reducing information costs in a state-owned firm. We show that debt contracts allow the government to avoid socially costly subsidies by letting unprofitable state-owned firms default. When the firm has private information, the government uses debt to reduce the firms` information rents. The option of default and privatize allows the government to stop subsidizing the firm. We identify the conditions under which information costs outweigh privatization costs and a positive debt level benefits governments.

  • The natural resources industry in decentralized Indonesia: how has decentralization impacted the mining, oil and gas industries?
    Duek, Ana, and Ridwan D. Rusli, Dec 2010, Publisher: CREA Discussion Paper 2010-25,
    Indonesia’s decentralisation laws have granted local governments more authority for generating higher own revenues and running more tailored decentralised public services. There is evidence, though, that inefficient and ineffective local governance continues to predominate after decentralisation. Regional autonomy, as defined in the decentralisation laws, has left some matters ambiguous, requiring more detailed implementing regulations. In the natural resource sector, in particular, the implementation of these laws has generated uncertainty for most social actors. Traditional as well as new formal and informal rules of conduct among a wide array of social actors continue to influence the management and allocation of the economic and social benefits of natural resources at the local level. All this has resulted in central-local policy inconsistencies and coordination issues, new hierarchies along geographic-political divisions, the wider spread of corruption, serious fiscal and environmental issues and adverse effects on the investment climate of the country.
