News - or foresight - about future economic fundamentals can create rational expectations equilibria with non-fundamental representations that pose substantial challenges to econometric efforts to recover the structural shocks to which economic agents react. Using tax policies as a leading example of foresight, simple theory makes transparent the economic behavior and information structures that generate non-fundamental equilibria. Econometric analyses that fail to model foresight will obtain biased estimates of output multipliers for taxes; biases are quantitatively important when two canonical theoretical models are taken as data generating processes. Both the nature of equilibria and the inferences about the effects of anticipated tax changes hinge critically on hypothesized information flows. Different methods for extracting or hypothesizing the information flows are discussed and shown to be alternative techniques for resolving a non-uniqueness problem endemic to moving average representations.

Recent financial crises including the ongoing one caused by the COVID-19 pandemic have consistently drawn attention to the need to strengthen the quality of public debt management in emerging markets and developing countries. Deeper and more efficient domestic government debt markets—being, a key segment of the LCBM for many emerging markets and developing economies—play a key role in reducing financial vulnerability to shocks and enable governments to finance critical economic and fiscal policy measures in response to them. Policymakers and international organizations have long recognized that developing and strengthening LCBMs is a key policy prescription to sound public debt management. Robust legal and regulatory frameworks are recognized as being critical building blocks for the structure, development and functioning of LCBMs. This Working Paper seeks to outline a strategically anchored methodology that can be applied to design, build and implement the legal and tax foundations for the development of LCBMs that would adequately address common challenges and impediments.
